      Abstract
      Preparation of two new Bis-N-heterocyclic carbene (Bis-NHC) platinum (ІІ) complexes have been described. The reaction of the Bis-NHC complex [PtMe2(Bis-NHC)], 1, in which Bis-NHC = 1,1’-methylene-3,3’-di(tert-Bu)imidazole ylidene, with two equivalent trifluoroacetic acid give the new Bis-NHC platinum [Pt(Bis-NHC)(CF3COO)2], 2. Complex 2 has been characterized by multinuclear NMR spectroscopy in solution and its solid state structure determined using X-ray crystallography. The mono-methyl Bis-NHC platinum(ІІ) complex, {PtMe(Bis-NHC)[OHB(C6F5)3]}, 3, has been prepared by the reaction of one equivalent B(C6F5)3 with [PtMe2(Bis-NHC)], 1. The mono-methyl complex 1 has a labile ligand...
