The first stable copper(II) complex containing four sulfide ligands: synthesis and structural characterization of [Pt2(dppe)2(µ-S)2] and [Cu{Pt2(dppe)2(µ3-S)2}2]2+
Abstract
The synthesis and crystal structure of the novel heteropolymetallic aggregate [{Pt2(dppe)2(µ3-S)2}2Cu]- [PF6]2 2 and of its precursor [Pt2(dppe)2(µ-S)2] 1 are reported; 2 has been further characterized by EPR and electronic spectroscopies and the hinged Pt2S2 rings in 1 and 2 have been rationalized by ab initio MP2 calculations.
