A homometallic mixed-ligand complex Pb(BTA)(phen)·H2O was synthesized by taking hydrated N,N′-bis(1H-tetrazolyl)amine (H2BTA·H2O), 1,10-phenanthroline (phen) and PbCl2as starting materials during this work. The complex was characterized by elemental analysis, IR, UV-Vis, FS and X-ray single-crystal diffraction. The results reveal that the coordination number of the Pb ion is four and the geometry can be regarded as a square-pyramidal geometry, with two N atoms of BTA2-and two N atoms of phen at the base. Crystal data for it, C14H11N11OPb, monoclinic, space groupC2/c,a= 9.420(2) Å,b= 22.943(6) Å,c= 15.286(4) Å,α= 90.000°,β= 105.760(4)°,γ= 90.000°,V= 3179.6(14) Å3,Z= 8, finalRindices [I> 2σ(I)],R1= 0.0241, wR2= 0.0471. The thermal stability of the complex was investigated by thermogravimetric analysis. The TG profile indicates that Pb(BTA)(phen) is thermally stable up to the temperature of 588.9 K.

Abstract A new mixed-ligand complex of copper(II) with 1,10-phenanthroline and 2-methyllactate was prepared. [Cu(HmL)2(phen)] ·2H2O (where HmL = monodeprotonated 2-methyllactic acid) was characterized by elemental analysis, IR, electronic and EPR spectroscopy, magnetic measurements at room temperature, thermogravimetric analysis and X-ray diffractometry. The copper atom is in a tetragonally distorted octahedral environment and the 2-methyllactato ligand is bidentately chelating. The presence of lattice water molecules mediates the formation of a three-dimensional network.

The crystals of 4,4-diaminodiphenyl sulfoxide have been obtained by evaporation from ethanol solution. The crystal structure of the 4,4-diaminodiphenyl sulfoxide was determined by X-ray single crystal diffraction analysis. The crystal data for 4,4-diaminodiphenyl sulfoxide: monoclinic, space groupP2(1)/c,a= 49.068(10) Å,b= 11.439(2) Å,c= 13.103(3) Å,V= 7347(3) Å3,Z= 24,Mr= 248.30,De= 1.347 g/cm3,T= 298(2) K,F(000) = 3120,R= 0.0786 andwR =0.2653. The compound forms three-dimensional network structure through hydrogen bonds and π-π interaction.
