<SUP>197</SUP>Au Mössbauer effect measurements of mixed-valence compounds and chelates of Au(III) with ligands of 1,10-phenanthroline, 8-quinolinol, and their derivatives have been carried out. The Mössbauer data of Cs<SUB>2</SUB>Au<SUB>2</SUB>Cl<SUB>6</SUB>, Cs<SUB>2</SUB>AgAuCl<SUB>6</SUB>, and [Au(phen)Cl<SUB>2</SUB>]Cl show the existence of an interaction between metal atoms through Cl atoms. Although the metal-metal interaction in [Au(Hdmg)<SUB>2</SUB>][AuCl<SUB>2</SUB>] has been postulated by X-ray study, no such interaction was observed. Two kinds of 8-quinolinol Au(III) complexes which have <I>cis</I>-<I>trans</I> isomers are assigned to the compounds of the [Au(oxine)<SUB>2</SUB>][AuCl<SUB>4</SUB>] and [Au(oxine)Cl<SUB>2</SUB>] types.
