摘要

A two-dimensional lead complex, [Pb(C14N3O2H12S)(NO3)]n·nH2O, was prepared by the reaction of salicylyl-4-phenyl thiosemicarbazide and lead nitrate. The compound (C14H13N4O6PbS, Mr = 572.53) crystallizes in the monoclinic space group P21/c with a = 11.2984(2), b = 15.6628(7), c = 11.1118(2)A,β= 113.564(2)°, V = 1802.43(10)A3, Dc= 2.110 g/cm3, Z = 4,μt(MoKα) = 9.515 mm-1, F(000) = 1084, the final R = 0.0394 and wR = 0.0701 for 2552 observed reflections with I 〉 2σ(I). The Pb(Ⅱ) ion displays a distorted octahedron in which the hypothesized stereochemically active lone pair occupies the apex. The compound exhibits a two-dimensional network structure formed by the zigzag one-dimensional chains joined by two μ-O of two nitrate groups in overlapping. A large ring exists in the two-dimensional layers. The TGA of the title compound has been studied.
