Four novel silver(i) and lead(ii) halide compounds with the 4-methyl-1,2,4-triazole-3-thiol (Hmptrz) ligand, namely [Ag2(mptrz)(μ3-X)]n (X = I (1) and Br (2)) and [Pb4(μ4-O)(mptrz)4(μ2-X)2] (X = I (3) and Cl (4)), have been synthesized and characterized. The structures exhibit different dimensionality depending on the nature of the metal ions. Compounds 1 and 2 are isomorphous and have 2D layered structures based on inorganic [Ag2X2]n infinite chains (X = I and Br), in which the mptrz– ligand displays a novel pentadentate bridging coordination mode. Compounds 3 and 4 have similar structures and are composed of a discrete tetranuclear lead(ii) cluster featuring an oxygen-centred Pb4(µ4-O) tetrahedron. Compounds 1 and 2 display solid-state photoluminescent emission with the maximum at 589 and 420 nm respectively. Compounds 3 and 4 show solid-state photoluminescent emission with the maximum at 710 and 540 nm respectively. Additionally, compounds 1–4 were characterized by IR, elemental analysis, powder X-ray diffraction and thermogravimetric analysis.

AbstractA new metal-organic framework, [Pb(hmpcaH)2]n (1), has been hydrothermally synthesized from Pb(OAc)2 · 3H2O and 2-hydroxy-6-methylpyridine-4-carboxylic acid (hmpcaH2; 2), and characterized by IR spectroscopy, elemental and thermogravimetric analysis, and single-crystal X-ray diffraction. In complex 1, each hmpcaH− ligand represents a three-connected node to combine with the hexacoordinated Pb(II) ions, generating a 3D binodal (3,6)-connected ant network. The crystal structure of 2 was determined. The solid-state fluorescence properties of 1 and 2 were investigated.

The coordination chemistry of butane-2,3-dione bis (2′-pyridylhydrazone) towards the divalent first-row transition metals zinc and iron has been explored. Depending upon the conditions, the ligand in the six complexes was found to be either neutral, mono, or doubly deprotonated. The zinc(II) and iron(II) complexes were fully characterized by elemental analysis, mass spectrometry, and X-ray diffraction methods.

The reaction of N,O-bis(trimethylsilyl)hydroxylamine with potassium hydride in pentane affords a product of the formula {K6[OSiMe3]4[ON(SiMe3)2]2}, resulting from deprotonation followed by N-O bond cleavage and 1,2-silylshift. The compound was characterised by elemental analysis and by single crystal X-ray diffraction. The aggregate consists of a K3O3 bis-cubane core, with N(SiMe3)2 groups at the oxygen atoms shared by the two cubes, andMe3Si groups attached to the four O vertices. Two weak K···N interactions are also detected in the solid state structure.

A series of copper(ii) complexes of the ligand 2,6-bis(pyridin-3-ylethynyl)pyridine have been synthesised and characterised by 1H and DOSY NMR, IR and UV-Vis spectroscopies, mass spectrometry, elemental analysis and single crystal X-ray diffraction. In solution these systems display almost identical spectroscopic properties, however the solid state structures are shown to vary widely, depending upon the choice of anion. The tetrafluoroborate salt was revealed to be a discrete Cu2L4 cage-like helicate. The tosylate salt, whilst of the same Cu2L4 stoichiometry, was shown to be a coordination polymer. Finally the nitrate salt structure was observed to be a discrete Cu2L2 metallocycle.

The title CdIIcoordination polymer, [Cd(C10H8O4)(C12H12N6)0.5(H2O)]n, has been obtained by the hydrothermal method and studied by single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy and fluorescence spectroscopy. The compound forms a novel three-dimensional framework with 3,8-connected three-dimensional binodal {4.52}2{42.510.612.7.83} topology. An investigation of its photoluminescence properties shows that the compound exhibits a strong fluorescence emission in the solid state at room temperature.

The reaction of 1,3-bis(1H-benzimidazol-2-yl)-2-oxapropane (L) with Co(ClO4)2?6H2O in absolute ethanol produces di[1,3-bis(1H-benzimidazol-2-yl)-2-oxapropane-k2N,N?]cobalt(II)diperchlorate chelate complex ([Co(L)2](ClO4)2, 1). The complex 1 was characterized by elemental analysis, magnetic moment, molar conductivity, thermogravimetric analysis, FT-IR, UV-visible, mass spectrometry, and its solid state structure was determined by single crystal X-ray diffraction. According to the thermogravimetric analysis data, there is no any water coordinated or uncoordinated in 1 as well as elemental analysis. The complex 1 has 1:2 M:L ionic characteristic according to the molar conductivity. In the complex, the distances between the cobalt and the ethereal oxygen atoms (Co1-O2: 2.805(3); Co2-O1: 2.752(2) ?) show the semi-coordination bonding and the Co(II) ion is six-coordinated with a N4O2 ligand set, resulting in a distorted octahedron.

A novel zirconium(IV)-substituted tetramer polyoxotungstate, H6K4Na16[Zr4(β-GeW10O38)2(A-α-PW9O34)2]·37H2O, was synthesized hydrothermally and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, powder X-ray diffraction, energy-dispersive X-ray spectroscopy and single-crystal X-ray diffraction. The compound crystallizes in the monoclinic P2/n space group. The most remarkable feature is that the centrosymmetric Zr-based polyoxotungstate tetramer consists of dilacunary Keggin-type germanotungstate and trilacunary Keggin-type phosphotungstate units that are linked by ZrIV ions.

AbstractTwo metal-organic coordination polymers constructed from tris(p-carboxylphenyl)phosphine oxide (TPOH3), namely, [Zn(TPOH)(2,2′-bipy)(H2O)·H2O·DMF]n (1) and [Zn2(TPOH)2(1,4-bix)2·5H2O]n (2) (2,2′-bipy=2,2′-bipydine, 1,4-bix=1,4-bis(imidazol-1-ylmethyl)benzene), were synthesized and identified by IR, elemental analysis and single-crystal X-ray diffraction analysis. Both of the 2,2′-bipy and 1,4-bix ligands tailor the complexes 1 and 2 into chain structures. The thermal behavior and solid state photoluminescence properties correlated with the corresponding structural features were investigated.
