Binuclear pyrazolato-bridged platinum(II) complexes: synthesis, characterization and crystal structure

Abstract

Binuclear pyrazolato-bridged platinum(II) complexes of the type [Pt2Cl2(µ-L–L)2(PR3)2][L–L = pz (pyrazolate) or dmpz (3,5-dimethylpyrazolate); PR3= PEt3, PMe2Ph or PMePh2] have been prepared by the reaction of [Pt2Cl2(µ-O2CMe)2(PR3)2] with Hpz or Hdmpz. All the complexes were characterized by elemental analysis and 1H and 31P NMR data. A single-crystal structure analysis of a representative complex, [Pt2Cl2(µ-dmpz)2(PMePh2)2], is also reported. Crystals are orthorhombic, with space group Pbca and unit-cell dimensions a= 17.701(9), b= 24.906(8), c= 16.976(7)Å. The structure was refined to final R= 0.040 for 3857 reflections with I[gt-or-equal] 3.0σ(I).
