The reaction ( 1 1) between [Au(2-C₆H₄CH₂NMe₂)Cl₂] and [HgPh₂] gives [Au(2-C₆H₄CH₂NMe₂)(Ph)Cl]. From this complex, the neutral [Au(2-C₆H₄CH₂NMe₂)(Ph)X] (X : Br, I, CN, MeCO₂) complexes are obtained by reaction with X^- salts. Cationic complexes [Au(2-C₆H₄CH₂NMe₂)(Ph)L]ClO₄ (L : pyridine, tetrahydrothiophene) are obtained by treatment of [Au(2-C₆H₄CH₂-NMe₂)(Ph)Cl] with ClO₄^- and the relevant ligand L. The complex [Au(2-C₆H₄-CH₂NMe₂)(Ph)Cl] crystallizes in two modifications, both with three independent molecules in the asymmetric unit. The AuN and AuCl bonds are long, consistent with the appreciable trans influence of the C-donor ligands. The molecules differ somewhat in the orientation of the rings.
