The hydrothermal reaction of ZnO, H3PO4(85%), (H2NCH2CH2)2NH and H2pydc results in the formation of a discrete mononuclear zinc(II) complex Zn(Hpydc)2(H2O). It crystallizes in monoclinic space group C2/c with a = 17.9947(8), b = 7.1875(3), c = 12.5895(4) , b = 110.802(2), V = 1522.14(10) 3, Z = 4, Mr = 415.61, (C14H10N2O9Zn), Dc = 1.814g/cm3, = 16.71cm-1, F(000) = 840, R = 0.0505, wR = 0.1144. Each zinc(II) is coordinated to two nitrogen and three oxygen atoms of which two nitrogen and two oxygen atoms are from two pydc ligands, and one oxygen atom from the coordinated water molecule to form an irregular polyhedral geometry. The complex is linked further into a three-dimensional structure through the weak interactions of hydrogen bonds between the two oxygen atoms. IR spectrum of the complex is also discussed.

A new octanuclear VSCu cluster {V2S6Cu6}(PPh3)6(O)22CH2Cl2CH3OH 1 has been prepared by extraction with CH2Cl2 of a solid mixture of (NH4)3VS4, Cu(PPh3)2Cl and NEt4Br, and its structure has been determined by single-crystal X-ray diffraction. Crystallographic data: C111H98Cl4Cu6O3P6S6V2, Mr = 2248.99, triclinic space group P , a = 13.751(6), b = 15.509(4), c = 15.642(5) ? a =114.34(2), b = 98.35(3), g = 110.43(3) , V = 2679.83 3, Z = 1, Dc = 1.538 g/cm3, F(000) = 1262, m (MoKa) = 16.9 cm-1, the final R = 0.079 and Rw = 0.083 for 5504 observed reflections with I > 2s(I). The structural determination shows that the skeleton can be described as a metal-sulfur dodecahedral cage fused by two incomplete cubane-like [VS3Cu3] subunits centrosymmetrically connected by CuS and weak CuCu bonds. The six copper and two vanadium atoms display a slightly distorted cubic array with a m4-S atom on each face of the metal cube. The selected IR, electronic and 51V NMR spectra have also been reported.

Crystal structure determination shows that the neighboring lanthanum(III) and zinc(II) ions are bridged by three bidentate m-cyanobenzonate ligands in the syn-syn fashion to form a pair of dinuclear [LaZn(m-CNC6H4COO)3(Py)(C2H5OH)] subunits, being linked together by two bidentate and two tridentate m-cyanobenzonate groups in the syn-syn and syn-anti modes, respectively, to construct a tetranuclear La-Zn complex [La2Zn2(m-CNC6H4COO)10(Py)2(C2H5OH)2].

The inter-diffusion of N,N-dimethylformamide solution of Zn(phen)2Cl2 and (NH4)2MS4 (M = W, Mo) in an H-shape tube produced crystals of Zn(phen)2WS4 1 and Zn(phen)2MoS4 2 (phen = 1,10-phenanthroline). The structures of isomorphous complexes 1 and 2 have been determined by X-ray single-crystal structure analyses. Four nitrogen atoms from the phenanthroline ligands and two sulfur atoms from the MS42- anion forming a distorted octahedron coordinate each zinc atom. Through p-p interactions of adjacent aromatic rings of the phenanthroline ligands, a quasi one-dimensional zigzag-stacking column is formed in each complex.
