Crystal structure of di-µ-pentafluorobenzenethiolato-trans-bis[(pentafluorobenzenethiolato)(triphenylphosphine)palladium(II)]: a second crystal form

Abstract

The structure of a second crystal form of the title compound has been determined from three-dimensional X-ray data collected photographically. This form is monoclinic, space-group P2₁/c, with Z= 2 in a unit cell of dimensions: a= 1·32, b= 1·64, c= 1·51 nm, β= 96°(all ± 1%). The structure was solved by conventional Patterson and Fourier methods and refined by least-squares techniques to R 0·128 for 2230 independent reflections. The ligands are approximately square planar about each palladium atom and the dimer possesses a centre of symmetry so that the non-bridging pentafluorobenzenethiolato-ligands are in the trans-configuration. It is suggested that the crystal structure also includes molecules of ethanol.
