    ABSTRACT: In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

    ABSTRACT: In the title compound, [Zn(2)(C(36)H(42)N(4)O(2))(CH(3)COO)(2)]·2CH(3)CH(2)OH, a centrosymmetric dinuclear zinc macrocyclic complex is accompanied by two half-occupied ethanol solvent molecues resulting in a 1:2 macrocycle-solvent composition. The Zn(II) atom has a square-pyramidal geometry arising from an N(2)O(3) donor set, being coordinated by two N atoms and two O atoms from the macrocyclic ligand in the equatorial sites and one O atom from an acetate anion in the apical site. The two Zn(II) atoms are linked by two phenolate O atoms, generating a four-membered Zn(2)O(2) ring at the centre of the macrocycle. The tert-butyl group shows rotational disorder over two sets of sites in a 0.552 (12):0.448 (12) ratio. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds are seen and a short intra-molecular C-H⋯O contact occurs.

    ABSTRACT: Two coordination polymers constructed from two structurally related ligands, 4,4′-bis(imidazol-1-ylmethyl)benzene (L1) and 4,4′-bis(imidazol-1-ylmethyl)bibenzene (L2) have been synthesized, [Zn2(ODPT)(L1)]·3H2O (1) and [Zn2(ODPT)(L2)2] (2), where H4ODPT is 4,4′-oxidiphthalic acid. Their structures have been determined by single crystal X-ray diffraction analyses. In 1, two kinds of L1 ligands coordinate to chiral centers Zn(II) cations to form two types of zigzag chains, which entwine each other to generate the snakelike chains. The phthalic groups from ODPT4− ligands link Zn(II) cations to form a right-handed 21 helical chain. This helical chain and the entwined snakelike chains entangle together to form a chiral subunit by co-ZnII cations. Then, intramolecular oxygen atoms from ODPT4− ligands bridge these subunits to extend a chiral three-dimensional framework with (52·84)(53·62·7)2 topology. In 2, Zn(II) cations are connected by ODPT4− anions and one kind of L2 ligand to form a double helical chain, which is linked by other helical chain constructed by other kind of L2 ligand and Zn(II) cation to generate a 3D framework. Two kinds of networks showing opposite helical units interpenetrate each other giving rise to a 2-fold interpenetrating network with a (3·6·74)(32·72·82)(64·72) topology. By careful inspections of two structures, we find that Zn(II) cations, the ODPT4− anions, and N-donor ligands show the same coordination modes or analogous configurations. Compound 1 is a chiral structure, and 2 is an achiral framework. The compounds are also characterized by elemental analyses, IR spectra, and thermogravimetric analyses. In addition, the luminescent properties of these compounds are discussed.

    ABSTRACT: Inorganic-organic hybrid materials based on Keggin polyoxometalate building blocks combined with Cu(II)/Cu(I) and flexible fluconazole ligand [1-(2,4-difluorophenyl)-1,1-bis[(1H-1,2,4-triazol-1-yl)methyl]methanol] (Hfcz) have been obtained by hydrothermal methods, namely, [Cu(II)(2)(Hfcz)(4)(SiW(12)O(40))].3H(2)O (1), [Cu(II)(4)(fcz)(4)(H(2)O)(4)(SiMo(12)O(40))].6H(2)O (2), [Cu(II)(2)(fcz)(2)][Cu(II)(4)(fcz)(4)(SiW(12)O(40))][Cu(II)(2)(fcz)(2)(H(2)O)(2)(SiW(12)O(40))].6H(2)O (3), (Et(3)NH)(2)[Cu(I)(2)(Hfcz)(2)(SiW(12)O(40))].2H(2)O (4), (Et(3)NH)(2)[Cu(I)(2)(Hfcz)(2)(SiW(12)O(40))].H(2)O (5) and [Cu(I)(4)(Hfcz)(4)(SiMo(12)O(40))] (6). Their structures have been determined by single-crystal X-ray diffraction analyses, and the compounds are further characterized by elemental analyses, IR spectra and thermogravimetric (TG) analyses. In 1, Cu(II) cations are bridged by fluconazole ligands to form a 3D lvt coordination polymeric network, which is connected by (SiW(12)O(40))(4-) anions to form a complicated 3D (4,6)-connected framework with the topology of (4(2).6(4))(4(6).6(7).8(2))(2). In 2, two fcz(-) anions chelate two Cu(2+) cations to form a [Cu(fcz)](2)(2+) dimer, which is bridged by (SiW(12)O(40))(4-) polyanions to generate a 2D (4,4) grid. Compound 3 is formed by three types of co-crystallizing subunits including a dimer [Cu(fcz)](2)(2+), a dumbbell molecule [Cu(4)(fcz)(4)(SiW(12)O(40))] and an infinite chain {[Cu(2)(fcz)(2)(H(2)O)(2)(SiW(12)O(40))](2-)}(infinity). In compounds 4 and 5, Hfcz ligands link Cu(+) cations to generate 1D coordination polymeric units, and (SiW(12)O(40))(4-) polyanions connect these metal-organic units to form two types of (6(3)) sheets which are topological isomerism. In compound 6, (SiMo(12)O(40))(4-) polyanions fixed in Cu(I)-Hfcz square rings are further extended into a 2D sheet via linking Cu(I) atoms of different rings. By carefully inspection of the structures of 1-6, it is believed that various transition-metal organic units and Keggin polyanions with different coordination modes are important for the formation of the different structures. In addition, electrochemical behaviors of compounds 1, 2, 5 and 6 have been investigated.

Their structures have been determined by single crystal X-ray diffraction analyses. All compounds are also characterized by elemental analyses, IR spectra, and thermogravimetric (TG) analyses. Compound 1 exhibits a two-dimensional (2D) layer structure with tetra-nuclear zinc clusters as building units, and intermolecular π···π stacking interactions link these sheets to a three-dimensional (3D) supramolecular structure. Compound 2 shows infinite chains and is extended into a 2D supramolecular sheet by intermolecular hydrogen bonds. The structure of 3 is built by L3 ligands connecting ODPT-Zn double-chains to a 3D network with a (42·6·102·12)(42·6)(102·12) topology. Compound 4 is isostructural with compound 1. In 5, partly deprotonated H2ODPT2− anions link the L2-Cd 24-membered rings to generate an infinite chain that extends into a 2D supramolecular sheet by intermolecular π···π stacking interactions. In 6, L3 ligands and the ether O atoms of HODPT3− anions link Cd−O chains formed by phthalic groups into a 3D network. In addition, the luminescent properties of these compounds are discussed.

    ABSTRACT: The centrosymmetric title compound, [Zn2(C22H22N4O2)(C4H7O4)2], is a dinuclear zinc(II) complex. Each ZnII atom has a square-pyramidal geometry with N2O3 donors, being coordinated by two N atoms and two O atoms from the 10,21-dimethyl-3,6,14,17-tetraazatricyclo[17.3.18,12]tetracosa-1(23),8,10,12(24),19,21-hexaene-23,24-diolate ligand and one O atom from a maleate anion. The two pentacoordinated ZnII atoms are linked by two phenolate O atoms. This leads to the formation of a four-membered Zn2O2 ring. The molecule exhibits a strong intramolecular O—H...O hydrogen bond, with an O...O distance of 2.480 (2) Å.

The chains are further connected through hydrogen-bonding interactions between the water molecules and the carboxylate O atoms of the BA anions, resulting in a two-dimensional supramolecular network. The C atom and H atoms of the ethyl chain are disordered over two positions with refined occupancies of 0.583 (12) and 0.417 (12).

In compound 1, the L ligand coordinates with two Cu(II) atoms to form a [Cu2L]2+ unit. In compound 2, two ox anions chelate to one Cu(II) atom to form a [Cu(ox)2]2− unit. The (H6L)4+ acts as a counter ion. The whole structures of 1 and 2 feature three-dimensional (3D) supramolecular architectures connected by weak Cu⋯O and hydrogen-bonding interactions, respectively. In compounds 3–5, the [M2L]2+ cations are bridged by nds, m-bdc and ox anions to form chains, respectively. The chains of 3 and 4 are further linked by hydrogen-bonding interactions into 2D and 3D supramolecular architectures, respectively. In compound 6, the macrocyclic L anion coordinates to two Cd(II) atoms to form a [Cd2L]2+ cation. The final structure of 6 exhibits a 3D supramolecular architecture linked by hydrogen bonds. In compound 7, Cd(II) atoms are linked by L anions to form two types of [Cd2L]2+ cations. One type of [Cd2L]2+ cations are bridged by btec anions to generate a polymeric anion chain, whereas the other [Cd2L]2+ cations are free. Further, the polymeric anion chains and the [Cd2L]2+ cations are linked by hydrogen bonds to generate a 2D supramolecular layer. In compound 8, btec anion bridges the [Ni2L]2+ cations to yield a 2D layer. Thermogravimetric analyses (TGA) for the compounds 1–8 have been investigated. In addition, the magnetic property for 1 and the luminescent properties for compounds 3–7 have also been studied.
