The bridging phosphido complex [NiCp(μ-PHMes)]₂ (1, Mes = 2,4,6-Me₃C₆H₂) was prepared from NiCp₂ and PH₂Mes. Deprotonation and methylation of 1 yields (NiCp)₂(μ-PHMes)(μ-PMeMes) (4) and [NiCp(μ-PMeMes)]₂ (6) via observable anionic phosphinidene intermediates. NMR spectroscopy was used to characterize syn and anti isomers of 1, 4, and 6, and the structures of anti-1a and syn-6b were determined by X-ray crystallography.
