Sažetak

The complex trans-PtCl2(8-dqmp)2 – trans-dichloro-bis(diethyl 8-quinolylmethylphosphonate-κN)platinum(II) – has been synthesized and the molecular structure has been determined by a rystallographic study. The platinum atom has a slightly distorted trans square-planar configuration with Pt1–N1 = 2.042(4) and Pt1–Cl1 = 2.306(1) Å. The dihedral angle between the Pt coordination plane and the mean plane of the 8-quinolylmethyl moiety is 65.1(1)°. The complex reveals a very interesting feature: a very short methylene proton–platinum distance of 2.309(5) Å 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%.
