Article abstract of DOI:10.1039/DT9800002060

By treating (M = Pd or Pt) with C6H5C(O)NHOH, C6H5(NH)NHOH, and p-RC6H4C(O)NHNH2 in ethanol, the complexes , , and (R = H, CH3, or NO2) respectively have been obtained.The reactions of with RNHNH2 (R = H or C6H5) lead only to the zerovalent complex, , while by treating with C6H5NHOH the known complex is obtained.Reactions of the aroylhydrazidoplatinum complexes with molecular oxygen and mineral acids are also reported.The structure of the two title complexes has been determined by X-ray diffraction.The compound is orthorhombic and crystallizes in space group Pna21 with a = 17.365(6), b = 11.218(7), and c = 18.431(8) Angstroem, whereas the disordered is monoclinic and crystallizes in space group P2n1/m with a = 15.829(6), b = 12.269(5), c = 11.833(5) Angstroem, and β = 93.51(3) deg.Both structures have been solved by Patterson and Fourier methods, and refined to R 0.031 and 0.062 for 2057 and 2119 independent reflections, respectively.Both compounds, in the solid state, are essentially square-planar complexes of PtII.The differences between the two structures, which display different packing efficiency, are mainly due to the conformations of the phosphine groups, which are imposed by the chelating ligands.
