The solid-state X-ray structure of Tp’PtMe(2)H has been determined. This platinum(IV) hydride derivative is stable at room temperature and crystallizes in an orthorhombic cell (space group P-cmn, Z = 4, a = 8.1292(8) Angstrom, b = 13.3862(9) Angstrom, and c = 17.9670(16) Angstrom). The hydride ligand was not located. The complex was synthesized as one of a series of organometallic platinum(IV) derivatives with Tp’ (Tp’ = hydridotris(3,5-dimethylpyrazolyl)borate) in the coordination sphere. These octahedral platinum(IV) Tp’PtMe(2)X and Tp’PtPh(2)X complexes were prepared by formal oxidation of platinum(II) intermediates ([K][Tp’PtMe(2)] and [K][Tp’PtPh(2)]) with electrophiles (HX, Mel, I-2). Thermogravimetric analysis (TGA) was employed to determine the solid-state decomposition temperatures for these platinum(IV) oganometallic complexes.
