Synthesis and structure of [Au(CH2)2PPh2]2[SSC(NPh)(NHPh)]2,a gold(II) ylide dimer containing the first example of a sulphur-rich thiourea

Abstract

The reaction of SC(NHPh)₂ with [Au(CH₂)₂PPh₂]₂Cl₂ followed by addition of base has led to the isolation and X-ray crystal structure analysis of a gold(II) ylide dimer, [Au(CH₂)₂PPH₂]₂[SSC(NPh)(NHPh)]₂ which is the first example of a thiourea containing catenated disulphide co-ordinated to a metal centre.
