✦ Synopsis
A number of different complexation structures of 3,5, with gold(I) and iridium(III) were synthesized and characterized by 1 H, 13 C NMR spectra, X-ray crystallography, and elemental analysis. Mono-and di-nuclear gold(I) chloride complexes with cis-DHDAtBu were obtained by simple addition of gold(I) chloride to cis-DHDAtBu. A heterotrinuclear gold-platinum-gold complex (PtAu 2 Cl 4 (cis-DHDAtBu) 2 ) was obtained by complexation of a mononuclear platinum(II) complex (trans-PtCl 2 (cis-DHDAtBu) 2 ), which was obtained by complexation of cis-DHDAtBu with a half-equimolar amount of PtCl 2 (PhCN) 2 ,with a twice-equimolar amount of gold(I) chloride. An iridium(III) complex with cis-DHDAtBu (IrCl 3 (cis-DHDAtBu) 2 ) was prepared from hydrated iridium(III) chloride and cis-DHDAtBu. The complex comprises a five-membered chelate cis-DHDAtBu and an usual monodentate cis-DHDAtBu.
