[Pt2(μ-S)2(PPh3)4] 与一系列锌 (II) 和钴 (II) 配合物 ML2(其中 L 是 β-二酮配体 CH3COCHCOCH3、PhCOCHCOPh、CF3COCHCOTh (Th=2-噻吩基)] 反应,可合成加合物 [Pt2(μ-S)2(PPh3)4M(二酮)]+,分离其 BPh4- 盐的产率适中。通过单晶 X 射线衍射研究对乙酰丙酮钴和乙酰丙酮锌配合物进行了表征,揭示了具有四面体异金属中心的同晶结构。
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.
