Complexes of platinum(II) with aromatic nitro compounds of the general formula PtCl(DMSO)(C6H3NO2R), where R=H, Cl, CH3, were synthesized. Their electronic and IR spectra were measured and discussed. The catalytic activity of the complexes in the hydrogenation reaction of the aromatic nitro compounds was shown.
An x-ray investigation of the PtCl(DMSO)(C6H4NO2) complex was carried out, and it was shown that the platinum atom has a square planar coordination and forms a five-membered metallo-ring, which includes one of the oxygen atoms of the nitro group and a carbon of the benzene ring at the ortho position with reference to the nitro group.
