Abstract

The reaction of a mononuclear NiII semiquinonediimine complex,viz., Ni[1,2-(NPh)(NH)C6H4]2, with silver triflate was investigated. The starting monomer was not oxidized in benzene or CH2Cl2 solutions; instead, a solvate of the complex with C6H6 was formed. According to the X-ray diffraction data, the solvate is characterized by an unusual molecular packing with short C−H(C6H6)... Ni and C−H(C6H6)... N−H contacts. An analogous effect is observed in the crystals of the solvate Pt[1,2-(NPh)(NH)C6H4]2·C6H6. Grinding of the nickel complex with silver triflate (the reagent ratio was 1:5) in the presence of acetone led to the oxidation of the complex, yielding tetrahydroimidazophenazinium triflate, whose structure was established by X-ray diffraction analysis.
