New platinum(II) complexes have been prepared as models for explaining the coordination of multiple β-diketonate ligands to give [Pt(O,O′-acac) (γ-acac)L] species. The new compounds containing both an O,O′-chelated acetylacetonate ligand and a sulfoxide in the platinum coordination sphere, [PtCl(O,O′-acac)(DMSO)] (1) and [Pt(O,O′-acac) (γ-acac) (DMSO)] (2), have been synthesised and characterised by 1H, 13C, 195Pt 1-D and 2-D NMR heteronuclear correlation spectroscopy and, in the case of 2, by X-ray crystal structure analysis also. Moreover, a new synthetic pathway to obtain the previously reported complex K[Pt(O,O-acac)(γ-acac)2] (3) has been developed. The data presented herein are consistent with a reaction mechanism which explains the subsequent steps of the coordination of multiple β-diketonate ligands to platinum(II) complexes, where the first species formed contains one O,O′-chelated acac group.
