The molecular and crystal structure of trans-dichloro(dimethylformamide) (2,6-lutidine)platinum(II)
The crystal structure of trans-[Pt(DMF)(2,6-lutidine)Cl2] has been determined by X-ray diffraction. The crystals are orthorhombic, space group Pbca, with a = 11.612(13), b = 26.504(33), c = 9.271(9) Å, and Z = 8. The structure was refined by full matrix least-squares analysis to a conventional R factor of 0.051 and a weighted Rw = 0.044. The coordination around the platinum atom is square planar. The 2,6-lutidine ring is perpendicular to the platinum plane. DMF is bonded to platinum through the oxygen atom. It is planar and makes an angle of 71 ° with the platinum plane. The cis–trans configuration of the [Pt(DMF)(L)Cl2] (L = pyridine derivative) complexes in DMF solution is discussed.
