Abstract

The platinum(II) tris(pyrazol-1-yl)borate complex [PtMe₂{(pz)₃BH-N,N‘}]^- reacts with phenol or aqueous HBF₄ in acetone to form the dimethylhydridoplatinum(IV) complex PtHMe₂{(pz)₃BH-N,N‘,N‘‘}. The complex decomposes above 140 °C in toluene-d₈ to give methane. Theoretical calculations at the SCF and MP2 levels for the species PtXMe₂{(H₂CNNH)₃BH-N,N‘,N‘‘} (where X = H, OH, Me and the fragment [(H₂CNNH)₃BH]^- is a model for [(pz)₃BH]^-) yield geometries that compare well with structural reports for Pt(OH)Me₂{(pz)₃BH} and PdMe₃{(pz)₃BH}.
