    ABSTRACT: A novel 3D Mn(II) coordination framework with Kagomé sublattice, [Mn(3)(py)(2)(nip)(2)](n) (py(-) = 2-((1H-tetrazol-5-yl)methyl)pyridine and nip(2-) = 5-nitroisophathalate), was in situ solvothermally synthesized and shows the coexistence of spin-canting, spin-frustration as well as field-induced metamagnetic and spin-flop transitions at 2.9 K.

    ABSTRACT: In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], the Ni(II) atom, located on a centre of inversion, is coordinated by two N atoms from two 2-(4-pyridyl-sulfan-yl)acetate ligands and four water O atoms in an octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate group of the anionic 2-(4-pyridyl-sulfan-yl)acetate ligands link these discrete mononuclear units into a three-dimensional network.

    ABSTRACT: Four 1,3-bis(1,2,4-triazol-1-yl)propane (btp)-based transition metal complexes, {[Zn(btp)3] ⋅(ClO4)2}n (1), [Zn(btp)2(dca)2]n (2), [Zn(btp)(NCS)2] (3), and [Mn(btp)2(NCS)2]n (4), have been obtained by introducing small anionic coligands and structurally characterized by single crystal X-ray diffraction, elemental analysis, IR spectra, thermogravimetric curves, and solid luminescence spectra. Structural determinations reveal that the polymeric triple-stranded chain for 1 without coligand is changed into 1-D double-stranded chains for 2 and 4, and discrete binuclear structure for 3. Compared with 1, the mixed-ligand complexes are moderately destabilized for 2 and 4, and slightly enhanced for 3. Additionally, the four solid complexes exhibit strong emissions, suggesting their potential applications as luminescent materials.

    ABSTRACT: Self-assembly of flexible 1,3-bis(1,2,4-triazol-1-yl)propane (btp), inorganic Cu(II) salt and rigid benzene-based carboxylate coligand generates four complexes, {[Cu(btp)2(CH3OH)(H2O)]·H2O·2ClO4}n (1), {[Cu(btp)(Hbtc)2]·0.5H2O}n (2), [Cu(btp)2(H3btea)2]n (3), and [Cu(btp)(nb)2] (4) (H3btc=1,3,5-benzenetricarboxylic acid, H4btea=1,2,4,5-benzenetetracarboxylic acid, Hnb=p-nitrobenzoic acid), which are fully structural characterized by single-crystal X-ray crystallography, elemental analysis, IR, and TG–DTA techniques. Structural determinations reveal that the polymeric two-dimensional (2D) Cu-btp grid-like layer for 1, 1D linear single- and double-stranded chains for 2 and 3, as well as the discrete binuclear structure for 4, are jointly directed by the coordination polyhedrons of the Cu(II) ion and the exo-bidentate bridging btp core ligand with various conformations. The theoretical calculations suggest that the trans–trans btp is the most stable conformation, and the metal binding site is collectively determined by the electron density of N donors and the spatial orientation of the btp ligand. Unexpectedly, the polycarboxylate anions in 1–4 can only act as terminal coligands not popular bridging connectors. The thermal stability of the resulting complexes is also compared.
