These species are formed by platinum(II)-mediated double coupling of 2,3-diphenylmaleimidine with both nitrile ligands. The formulation of the complexes was supported by satisfactory C, H, and N elemental analyses, which were in agreement with HRESI-MS, IR, and H-1 and C-13{H-1} NMR spectra. The structures of 10, 11 center dot 1/8nC(6)H(14), 15, 16 center dot CCl4, and 17 center dot CHCl3 were determined by single-crystal X-ray diffraction. Absorption and emission studies were performed on representative complexes 10, 15, and 18, and the results show weak phosphoresce",
