Abstract

The complex trans-[PtCl2(8-dqmp)(2)] - trans-dichloro-bis(diethyl 8-quinolylmethylphosphonate-kappa N)platinum(II) - has been synthesized and the molecular structure has been determined by a crystallographic study. The platinum atom has a slightly distorted trans square-planar configuration with Pt1-N1 = 2.042(4) and Pt1-Cl1 = 2.306(1) Angstrom. The dihedral angle between the Pt coordination plane and the mean plane of the 8-quinolylmethyl moiety is 65.1(1)degrees. The complex reveals a very interesting feature: a very short methylene proton-platinum distance of 2.309(5) Angstrom occupying approximately axial positions around the central metal atom for the hydrogen atom H10B. Refinement was performed by least-squares methods to a final R value of 3.02%.
