摘要：
Reactions of the complexes cis-[PtCl2(PPh3)(2)], [PdCl2(dppe)] (dppe?=?Ph2PCH2CH2PPh2) and the N,C-cycloaurated gold(III) complexes [AuCl2(2-benzylpyridyl)] and [AuCl2(C6H4CH2NMe2)] with the secondary dithiooxamide EtNHC(S)C(S)NHEt in refluxing methanol with Et3N base gave good yields of the respective neutral dithiooxamide complexes containing a doubly deprotonated dithiooxamide ligand. The Pt and Pd complexes, as well as [Au{SC(NEt)C(NEt)S}(C6H4CH2NMe2)], were characterized by single-crystal X-ray diffraction. In all complexes the ligand is S,S-bonded to the metal center. The complexes were also characterized by NMR spectroscopy and ESI mass spectrometry.
