Crystal and molecular structure of bis(N,N-diethyldithiocarbamato)palladium(II)

The crystal and molecular structure of bis(N,N-diethyldithiocarbamato)palladium(II), Pd(S₂CN(C₂H₅)₂)₂, has been determined by a three-dimensional X-ray analysis. The compound crystallizes in the tetragonal space groupP4₂/n with unit cell dimensionsa = 16·439(8) Å andc = 6·247(3) Å. The crystals are isomorphous with bis(N,N-diethyldithiocarbamato)platinum(II). Intensities were obtained with an automatic diffractometer. The structural parameters were refined by least-squares methods to a conventionalR factor of 0·038 for 600 non-zero observed reflections. The palladium is in planar coordination with four sulphur atoms, the two non-equivalent Pd-S bond lengths being 2·317(3) and 2·315(3) Å.The authors are grateful to Mr J. G. M. van Rens for providing the crystals and measuring the unit cell dimensions, to Professor J.J. Steggerda for his continuous interest and to Mr W.P.J.H. Bosman, Mr J.M.M. Smits and Mr J.A.B.C. Wolf for valuable assistance.
