    ABSTRACT: Two novel photoluminescent copper(I) complexes having the compositions [CuI(L1)(PPh3)2]NO3·3CHCl3(1) and [CuI(L2)(PPh3)2]NO3·H2O(2) with PPh3 = triphenylphosphine, L1 = cis-(±)-2-(2,5-di(pyridin-2-yl)-4,5-dihydro-1H-imidazol-4-yl)pyridine and L2 = 2,4,6-tris(2-pyridyl)triazine have been successfully synthesized and characterized by IR and 1H-NMR spectroscopy, FAB+ mass spectrometry and single-crystal X-ray diffraction analysis. Both complexes showed interesting photophysical properties, which were studied experimentally in solution and in the solid state by UV-Vis and fluorescence spectroscopy and theoretically using TD-DFT calculations.

    ABSTRACT: The asymmetric unit of the title compound, C9H6O6·3C5H5NO, contains one benzene-1,3,5-tri-carb-oxy-lic acid mol-ecule (BTA) and three pyridin-2-ol mol-ecules each present in the zwitterion form. In the crystal, these entities are linked through O-H⋯O(-) and N(+)-H⋯O(-) hydrogen bonds, forming sheets parallel to (10-1). These layers contain macrocyclic rings of composition [BTA]2[pyol]6 and with graph-set notation R (6) 8(44), which are stacked along c through π-π inter-actions [inter-centroid distances = 3.536 (2)-3.948 (3) Å]. They are inter-connected by N(+)-H⋯O(-) hydrogen-bonded chains of pyridin-2-ol mol-ecules running parallel to c, forming a three-dimensional network. There are also C-H⋯O hydrogen bonds present which reinforce the three-dimensional structure.

    ABSTRACT: The asymmetric unit of the title compound, C12H10BNO5·0.67H2O, contains three independent pyridinylboronic acid esters adopting zwitterionic forms and two water mol-ecules. The six-membered heterocyclic rings in the boronic esters have half-chair conformations and the deviations of the B atoms from the boronate mean planes range from 0.456 (3) to 0.657 (3) Å. All of the B atoms have tetra-hedral coordination environments, with B-O and B-C bond lengths of 1.446 (4)-1.539 (3) and 1.590 (5)-1.609 (5) Å, respectively. In the crystal, the ester and water mol-ecules are linked into a three-dimensional network by a large number of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. The crystal packing is further accomplished by π-π inter-actions, with centroid-centroid distances of 3.621 (4)-3.787 (4) Å.

    ABSTRACT: The asymmetric unit of the title hydrated complex salt, (C18H14N5)2[Pt(CN)4]·4H2O, consists of one 2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium cation, half a tetra-cyanidoplatinate(II) dianion, which is located about a crystallographic inversion center, and two water mol-ecules of crystallization. The Pt(II) atom has a square-planar coordination environment, with Pt-CCN distances of 1.992 (4) and 2.000 (4) Å. In the cation, there is an N-H⋯N hydrogen bond linking adjacent pyridinium and pyridine rings in positions 4 and 5. Despite this, the organic component is non-planar, as shown by the dihedral angles of 10.3 (2), 6.60 (19) and 15.66 (18)° between the planes of the central imidazole ring and the pyridine/pyridinium substituents in the 2-, 4- and 5-positions. In the crystal, cations and anions are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. Additional π-π, C-H⋯O and C-H⋯N contacts provide stabilization to the crystal lattice.

    ABSTRACT: In the title adduct, C5H5NO·C8H12O4, the heterocycle exists in its zwitterionic form. The cyclo-hexane ring exhibits a chair conformation with the carb-oxy-lic acid groups in equatorial and axial orientations. In the crystal, mol-ecules are linked through charge-assisted O-H⋯O(-), N(+)-H⋯O(-) and N(+)-H⋯O hydrogen bonds, and an additional series of C-H⋯O contacts, giving a pleated two-dimensional hydrogen-bonded network parallel to (-204).

    ABSTRACT: The title 2:1 co-crystal, 2CHN·CHO, crystallizes with one mol-ecule of 4-[()-2-(pyridin-2-yl)ethen-yl]pyridine () and one half-mol-ecule of terephthalic acid () in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOH⋯N synthons, forming linear aggregates of composition -----. Further linkage through weak C-H⋯O and C-H⋯π inter-actions gives two-dimensional hydrogen-bonded undulating sheets propagating in the [100] and [010] directions. These layers are connected through additional weak C-H⋯O contacts, forming a three-dimensional structure.

    ABSTRACT: The binuclear title compound, [Cu(2)(CH(3)CO(2))(4)(C(6)H(5)NO)], is located about a center of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6134 (5) Å] and bridged by four acetate ligands. Their distorted octa-hedral coordination geometry is completed by a terminal pyridine N atom of a 3-pyridincarboxaldehyde ligand. In the crystal, the complex mol-ecules are linked by C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane. These networks are linked via C-H⋯O hydrogen bonds involving inversion-related 3-pyridinecarboxaldehyde ligands, forming a three dimensional supra-molecular architecture.

    ABSTRACT: Three organic–inorganic hybrid compounds have been prepared by combination of the tripyridinium imidazole of cation [2,4,5-tri(4-pyridyl)imidazole] (L) and a series of perhalometallate anions to give, namely [H3L(CuCl4)]Cl (1), [(H3L)2(PdCl4)3]·4H2O (2) and [(H3L)2(PtCl4)3]·4H2O (3), which have been structurally characterized by single-crystal X-ray diffraction analysis, showing that the hydrogen bonding interactions of the resulting 1D, 2D, and 3D networks contain at least one of the following synthons: X–HClnM− [X = C, N, N+; n = 0,1,2; M = Cu(II), Pd(II), Pt(II)] The dimensions are enhanced further by strong X–HCl− (C, N+) and OHClnM− [n = 1,2; M = Pd(II), Pt(II)] hydrogen bonds. Additional weak C–HO, π–π stacking and ClCl interactions stabilize the crystal structures further.

    ABSTRACT: In the title compound, C(18)H(14)N(4)O, the mol-ecules are disordered about a crystallographic twofold axis, leading to 50:50 disorder of the O- and N-atom sites within the oxazole ring. As a consequence, symmetry-related oxazole C-N and C-O bonds are averaged. The oxazole ring makes a dihedral angle of 6.920 (1)° with the pyridyl ring in the 2-position and 60.960 (2)° with the pyridyl rings in the 4- and 5-positions.

    ABSTRACT: In the title organic salt, C(5)H(7)N(2) (+)·C(8)H(5)O(4) (-), the carb-oxy-lic group is nearly coplanar with the benzene ring [dihedral angle 1.9 (4)°] whereas the carboxyl-ate group is twisted relative to the benzene ring by 13.6 (4)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional framework consisting of stacks of alternating pairs of anions and cations exhibiting π-π stacking inter-actions with centroid-centroid distances in the range 3.676 (2)-3.711 (1) Å. The π-π stacks extend along [110] and [-110].

    ABSTRACT: The title compound, C(9)H(10)N(2)O(4)·H(2)O, was obtained as a zwitterion derived from the nucleophilic attack of 3-amino-pyridine on the fumaric α,β-system. Within the molecule, the amino-pyridine moiety and the carboxyl-ate and carb-oxy-lic acid fragments form dihedral angles of 68.6 (2) and 62.8 (2)°, respectively. The geometry adopted by the mol-ecule does not allow the formation of centrosymmetric dimeric hydrogen-bonded units; instead chains along the a axis are linked by COO-H⋯OOC motifs. These chains are inter-connected by N-H⋯O and O-H⋯O hydrogen bonds involving the carb-oxy-lic acid and carboxyl-ate units and the solvent water mol-ecules.

    ABSTRACT: Five metal complexes have been prepared by reacting 3- and 4-pyridineboronic acid (3- and 4-pba) with potassium tetrachloroplatinate (K2PtCl4) and hexachloroplatinic(IV) acid hydrate (H2PtCl6·aq): [4-pbaH]2[PtCl4], [3-pbaH]2[PtCl4], [4-pbaH][Pt(4-pba)Cl3], cis-[Pt(4-pba)2Cl2]·H2O, and cis-[PtIV(3-pba)2Cl4]·2H2O. All compounds have been characterized by single-crystal X-ray diffraction analysis, showing that the primary hydrogen bonding interactions of the resulting 1D, 2D, and 3D networks contain at least one of the following synthons: X-H···Cl2Pt− (X = C, N+), B(OH)2···Cl2Pt−, and B(OH)2···(HO)2B. The dimensions are enhanced further by secondary +N−H···ClPt, O−H···O, and O−H···ClPt hydrogen bonding interactions between donor and acceptor atoms located at the periphery of these synthons. Additional weak C−H···O, C−H···Cl, B···N, and π···π stacking interactions stabilize the crystal structures further.
