Abstract
A new Pb(II) one-dimensional coordination polymer {[Pb(PAA) 2] n ( 1), PAA − = phenylacetate} was synthesized by the reaction of Pb(CH 3COO) 2 · 3H 2O and ligand phenyl acetic acid. Compound 1 was structurally characterized by single-crystal X-ray diffraction. The crystal structure of this compound consists of one-dimensional polymeric units of [Pb(PAA) 2] and the coordination number of Pb II ions is six. The lead atoms have irregular coordination sphere containing stereo-chemically active lone pair and tetra-hapto (η 4) interactions, thus attaining a total hapticity of 10 with environment C 4O 6Pb. The thermal stability of compound 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The results of studies of the stoichiometry and formation of complex 1 in methanol, ethanol and acetonitrile solutions were found to be in support of their solid state stoichiometry.
