Synthesis and Theoretical Studies of a Diorganohydridoplatinum(IV) Complex, PtHMe2\(pz)3BH-N,N',N''\} ([(pz)3BH]- = Tris(pyrazol-1-yl)borate).}

The platinum(II) tris(pyrazol-1-yl)borate complex [PtMe2{\{}(pz)3BH-N,N'{\}}]- reacts with phenol or aq. HBF4 in acetone to form the dimethylhydridoplatinum(IV) complex PtHMe2{\{}(pz)3BH-N,N',N''{\}}. The complex decomps. above ∼140° in toluene-d8 to give methane. Theor. calcns. at the SCF and MP2 levels for the species PtXMe2{\{}(H2C:N-NH)3BH-N,N',N''{\}} (where X = H, OH, Me and the fragment [(H2C:N-NH)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{\}}.
