The crystal and molecular structure of dichloro-(bis-1,2-diphenylphosphinoethane)platinum(II)

Crystals of PtCl2(PPh2)(CH2)2(PPh2) (1), produced from attempts to prepare hydridochloroplatinum complexes, are monoclinic, space groupP21/c, with four molecules in a unit cell of dimensionsa=11.478(3),b=13.263(2)c=16.343(3) Å, and β=99.00(2)°. The structure was solved by the heavy-atom method and refined by block-diagonal least-squares calculations with anisotropicthermal parameters;R=0.048 andR′=0.061 for 1843 observed reflections. The …
