  一些 Au(III) 和 Cu(I) 二硫代草酰胺配合物的热分析

  摘要：

  摘要 平面二硫代草酰胺与 Au(III)- 和 Cu(I)- 离子形成稳定的络合物。中性 Au(LH)X 2 (LH 2 =RHNCSCSNHR)-配合物分解而不形成任何中间体。离子 A[Au(L) 2 ] (A=Li, Na, K) 主要由晶格力稳定。在[Au(LH 2 )Br 2 ]Br-配合物中，每分子1HBr的释放分两步发生，以形成更稳定的Au(LH)Br 2 。中性的Cu(LH 2 ) 2 X (X=Cl, Br, I) 分解形成更稳定的Cu(LH 2 )X。Cu(LH 2 )X-配合物不成比例地形成(CuL) x 聚合物、Cu、配体和HX。Cu(CH 3 HNCSCSNHCH 3 )I 显示在 200°C 形成稳定的 Cu 4 (CH 3 HNCSCSNHCH 3 )I 4 和配体。

  In this article, the preparation, X-ray powder results and vibrational properties of a new type of complex with planar dithiooxamides are discussed. In acetonitrile, Cu(I) can form complexes with the formula Cu(LH(2))(2)X(1) (X = Cl, Br) where LH(2) is an N,N'-disubstituted dithiooxamide. Complexes with N,N'-dimethyldithiooxamide and N,N'-diethyldithiooxamide have been prepared. A thorough vibrational analysis with infrared and Raman techniques was performed, assisted by H/D and Cu-63/Cu-65 isotope substitution. The vibrational study indicates the presence of an inversion centre in the structure. This leads to the proposal of a very unusual six-coordinate structure for these compounds, with the two dithiooxamide ligands, having S-cis conformation, coordinated to the same copper and with the halogens bridged between two different copper atoms. Confirmation of this result was attempted by X-ray analysis, but although several methods were tried to obtain crystals, only powder X-ray data could be obtained, which could not give a definitive answer. Since such six-coordinate Cu(I) has never been described before, a less rigourous interpretation of the vibrational data was followed, leading to a square-pyramidal five-coordinate structure, with a rather weak bond between Cu(I) and a terminal halogen. The latter structure, with the data available up to now, seems a bit more likely, since five-coordination for Cu(I) has already been described.
