Sulfide-bridged aggregates from the metalloligand [Pt2(μ-S)2(PPh3)4] and β-diketonate complexes of cobalt(II) and zinc(II)

Reaction of [Pt2(μ-S)2(PPh3)4] with a range of zinc(II) and cobalt(II) complexes ML2, where L is a β-diketonate ligand CH3COCHCOCH3, PhCOCHCOPh, CF3COCHCOTh (Th = 2-thienyl)] permits the synthesis of adducts [Pt2(μ-S)2(PPh3)4M(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.

Zinc(II) and cobalt(II) β-diketonate adducts of the metalloligand [Pt2(μ-S)2(PPh3)4] have been prepared and characterised, including X-ray crystal structures on the complexes [Pt2(μ-S)2(PPh3)4M(CH3COCHCOCH3)]BPh4 (M = Co, Zn).Figure optionsDownload as PowerPoint slide
