摘要：

A thallium(I) one-dimensional polymer, [Tl(mu(4)-AB)](n) (1) [HAB = 4-aminobenzoic acid], has been synthesized and characterized. The single-crystal X-ray data of compound show the coordination number in the Tl-1 ions is five, the thallium atoms have irregular coordination sphere containing stereo-chemically active lone pair and bi-hapto (eta(2)) interactions, thus attaining a total hapticity of seven with environment C2O5Tl. The thermal stability of 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The ligand HAB and compound 1 are luminescent in the solution state, with emission maxima at 395 nm. The results of studies of the stoichiometry and formation of complex of 1 in DMF solution were found to be in support of their solid state stoichiometry. (c) 2007 Elsevier B.V. All rights reserved.
