CONTRIBUTIONS TO THE CHEMISTRY OF THIOCOMPLEXES NEW COMPLEX-COMPOUNDSOF GOLD(III) WITH AROMATIC THIOAMIDES

New complex compounds of Au(III) with thioamides of the phenylthioacet amide series and with thioamides of the dibenzofuran series are descri bed. A correlation of elemental analysis, UV, visible, IR spectral ana lysis and conductivity measurements, suggests that the compounds are o f [AuL2]Cl3 type (L=phenylthioacetamide, o-tolylthioacetamide, 2,5-dim ethylthioacetamide) and [AuLCl2]Cl type (L=diphenyltioacetamide, 3-thi oacetylamino-dibenzofuran, 3-thiobenzoylamino-dibenzofuran and 3-thiof uroylamino-dibenzofuran). The chemical bond implies the participation of both a sulphur atom and a nitrogen of the ''thione'' group in coord ination to the metal. Electronic spectra show a plane-square geometry of the complexes.
