摘要

A new complex [Pb（phen）2（4-NBA）]2·2（NO3）·H2O（phen = 1,10-phenanthroline,4-NBA = 4-nitrobenzoate） has been hydrothermally synthesized and structurally determined by single-crystal X-ray diffraction,elemental analyses and IR spectroscopy.The complex crystallizes in monoclinic,space group P21/c with a = 13.416（3）,b = 14.065（3）,c = 16.845（3）（A°） ,β = 110.55（3）o,V = 2976.5（10）（A°）^3,Z = 2,Dc = 1.796 g/cm^3,F（000） = 1564,GOOF = 0.962,the final R = 0.0686 and wR = 0.1746.The crystal structure shows that the lead ion is coordinated with two carboxylate O atoms from the 4-NBA anion,and four N atoms from two phen molecules,forming a slightly distorted pentagonalbipyramidal coordination geometry.It is further extended by various supramo-lecular interactions to form a three-dimensional supramolecular network.The TG analysis result shows that this complex begins decomposing at 30 ℃ and decompounding completely at 733 ℃.
