Reaction of [Pt-2(mu-S)(2)(PPh3)(4)] with a range of zinc(II) and cobalt(II) complexes ML2, where L is a beta-diketonate ligand CH3COCHCOCH3, PhCOCHCOPh, CF3COCHCOTh (Th = 2-thienyl)] permits the synthesis of adducts [Pt-2(mu-S)(2)(PPh3)(4)M(diketonate)](+), isolated as their BPh4- salts in moderate yields. The cobalt and zinc acetylacetonate complexes were characterised by single-crystal X-ray diffraction studies, which reveal isomorphous structures, with tetrahedral heterometal centres.
