High-Valent Pyrazolate-Bridged Platinum Complexes: A Joint Experimental and Theoretical Study.

ABSTRACT: Complexes [{Pt(C^C*)(μ-pz)}₂] (HC^C*_A = 1-(4-(ethoxycarbonyl)phenyl)-3-methyl-1H-imidazol-2-ylidene 1a, HC^C*_B = 1-phenyl-3-methyl-1H-imidazol-2-ylidene 1b) react with methyl iodide (MeI) at room temperature in the dark to give compounds [{Pt^IV(C^C*)Me(μ-pz)}₂(μ-I)]I (C^C*_A 2a, C^C*_B 2b). The reaction of 1a with benzyl bromide (BnBr) in the same conditions afforded [Br(C^C*_A)Pt^III(μ-pz)₂Pt^III(C^C*_A)Bn] (5a), which by heating in BnBr(l) became [{Pt^IV(C^C*_A)Bn(μ-pz)}₂(μ-Br)]Br (6a). Experimental investigations and density functional theory (DFT) calculations on the me
