New complexes of the type [AuCl2L] have been prepared, where L is a chelate consisting of a phenyl group bearing an N-donor substituent (oxazoline and/or dimethylaminomethyl). The structures of two of these, together with that of [AuCl{C6H3(CH2NMe2) 2-2,6}]2[Hg2Cl6], have been determined by X-ray crystallography; the gold atoms exhibit strict square-planar geometry in all cases. The chloride ligands undergo ready substitution by other halides, thiocyanate, acetate or diethyldithiocarbamate. The monodithiocarbamate complexes [Au(S2CNEt2)L]+ contain chelated S2CNEt2 groups whereas in [Au(S2CNEt2)2L] the L ligand is monodentate (through C), one S2CNEt2 is monodentate, the other bidentate; in solution the two S2CNEt2 ligands appear equivalent on the NMR time-scale, indicating a rapid equilibrium between the two possible forms.
