Synthesis and crystal structure of copper and gold complexes of 1,2,5-thiadiazole-3,4-dithiolate. Charge transfer salt with TTF

The M(tdas)2 complexes (tdas2−=1,2,5-thiadiazole-3,4-dithiolate) with M=CuII, CuIII and AuIII were obtained as tetrabuthylammonium and tetraphenilphosphonium salts and characterised. The crystal structure of (n-Bu4N)n[M(tdas)2], M=Cu(2) and Au(4) were determined by X-ray crystallography as well as that of the charge transfer salt (TTF)2[Au(tdas)2]2 (5).
