摘要：

A 3D polymer built with the assistance of eta(2) Ag-C bonds, [Ag-2(mu(8)-SB)] (1) [H2SB = 4-[(4-hydroxyphenyl) sulfonyl]-1-benzenol], has been synthesized and characterized and its structure was determined by X-ray crystallography. In addition to the coordination to the O atoms of SB2-the Ag atoms also form strong eta(2) Ag-C bonds, resulting in the formation of an AgO2C2 environment. The thermal stabilities of 1 and of its thallium(I) analogue, [Tl-4(mu(8)-SB)(2)] (2), were studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The ligand and compounds 1-2 are luminescent in the solution state, with emission maxima at 380, 353 and 468 nm, respectively. The results of studies of the stoichiometry and formation of complexes of 1 and 2 in acetonitrile and DMF solutions were found to be in support of their solid state stoichiometry.
