Abstract:Summary A new platinum complex of 1-methyl-5-nitroimidazole has been obtained and characterized by elemental analysis, i.r. and n.m.r. spectroscopy. The structure of PtI2-(C4 H5N3O2)2] has been determined by single-crystal X-ray diffraction. The crystals are triclinic: P1, a = 15.640(3), b = 12.617(2), c = 6.701(1) angst, agr = 102.77(5), beta = 101.15(5), gamma = 100.71(5)°, V = 1228.6(3) angst3, Z = 3, Dx = 2.851(6) Mg m–3, lambda(MoK agr) = 0.71069 angst, mgr = 12.85 mm, F(000) = 948, final R = 0.038 for 2859 reflections. The complex consists of monomeric PtI2(1-methyl-5-nitroimidazole)2 units. The coordination geometry is square-planar. The two 1-methyl-5-nitroimidazole ligands are trans coordinated to platinum.
