  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。

  The infrared spectra of complexes with planar dithiooxamides Part VIII. The Au(III) complexes

  摘要：

  In acid media Au(III) forms complexes with dithiooxamide (DTO) of formula [Au(DTO)(DTO)-H]Cl-2 and with N,N-dimethyldithiooxamide (DMDTO) of formula [Au(DMDTO-H)(1)X(2)] (X is Cl or Br) and [Au(DMDTO)(1)Br-2]Br. In strong alkaline media for the N,N'-disubstituted dithiooxamides a new type of complex could be obtained with formula A[Au(L)(2)] (A is Li, Na or K; LH(2) is DMDTO or N,N'-diethyldithiooxamide (DEDTO)). Infrared and Raman spectroscopy has been used to study of these complexes and also some thermal analysis is included. A thorough analysis of the vibrational spectra is carried out to reveal the structure of these complexes. From this it is concluded that all complexes have a square-planar geometry around Au(III) and that in all cases the dithiooxamides act as bidentate ligands coordinating through both sulphur atoms forming chelate ring systems. For the complexes formed in acid media special attention is given to the effect of hydrogen bonding on the infrared spectra, while for the complexes obtained in alkaline media the influence of the alkali counter-ion is investigated. From the TG data it is concluded that the forces in the ionic lattice of the A[Au(L)(2)] complexes follow the series Li > Na > K.
