摘要：

Structural organization and thermal behavior of a new polymeric heteronuclear of gold(III)-zinc-dibutylammonium complex ([NH2(C4H9)(2)][Au{S2CN(C4H9)(2)}(2)][ZnCl4]) (n) (I), obtained by a heterogeneous reaction between freshly precipitated binuclear zinc dibutyldithiocarbamate [Zn-2{S2CN(C4H9)(2)}(4)] and a H[AuCl4] solution in 2M HCl, is studied. According to single crystal XRD data the crystal structure of the obtained compound is determined and its main structural units are complex [NH2(C4H9)(2)](+) and [Au{S2CN(C4H9)(2)}(2)](+) cations and complexD mu [ZnCl4](2-) anions. Dibutylammonium cations are hydrogen bonded to tetrachlorozincate ions, forming zigzag polymer chains. On the side of the chains there are discrete complex [Au{S2CN(C4H9)(2)}(2)](+) cations characterized by a planar tetragonal structure and a uniform spatial orientation. The thermal behavior of I is investigated by synchronous thermal analysis. The multistage process of thermal destruction involves the thermolysis of the cation and anion parts (with the release of metallic gold, zinc chloride and a partial formation of zinc sulfide).
