【 摘 要 】

In this article we present the synthesis of the compound [Cd8Cl2Se(SePh)12(PCy3)2]·2.5CH3OH by the reaction of Cd(SePh)2 with CdCl2 and PCy3 in methanol in a stainless steel sealed reactor under solvothermal conditions at 130 ºC. This compound represents the latest result of our systematic work on the growth of molecular clusters from Cd(SePh)2 as starting material. Their importance is based not only on the properties of the new compounds, but also by their possible use, for example, in the development of new methods via a ''bottom up" strategy to obtain different clusters from single components like M(ER)2 (M = metal, E = chalcogen, R = alkyl or aryl). The title compound was characterized by single crystal X-ray diffractometry, elemental analysis, thermogravimetrical analysis and the UV-Vis spectroscopy. These results were correlated with data calculated by DFT, density functional theory.
