STRUCTURE OF (AD,BE-BIS[(8-DIMETHYLAMINO-KAPPA-N)NAPHTHYL-KAPPA-C1])-F-ETHYL-C-IODOPLATINUM(IV)

[Pt(C12H12N)2(C2H5)I], M(r) = 691.5 1, monoclinic, P2(1)/n, a = 14.902 (1), b = 10.815 (4), c = 14.941 (1) angstrom, beta = 103.29 (1)-degrees, V = 2343.3 (3) angstrom3, Z = 4, D(x) = 1.960 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 73.7 cm -1, F(000) = 1320, T = 294 K, R = 0.030 for 4204 unique observed diffractometer data with I > 2.5-sigma(I). The platinum(IV) cation is coordinated by two C,N-chelate bonded 8-dimethylamino-1-naphthyl (dman) monoanionic ligands as well as the ethyl and iodo anions which are mutually in cis orientation. As oxidative addition reactions of primary alkyl halides to organometal-d8 complexes generally yield trans-(alkyl)(halide) products, the observed formation of the cis isomer in the reaction of Pt(dman)2 with EtI is an exception: the reaction with MeI affords the trans-(Me)(I) product.
