Structural Chemistry of the Platinum Group-Metals: MCl₂(bpy) (M = Pd, Pt, bpy = 2,2′-Bipyridine)

Abstract

A singlecrystal X-ray structure determination of (2,2′-bipyridine)dichloropalladium(II), iso- morphous with the 'yellow' form of the platinum(II) analogue, has been carried out. Crystals are orthorhombic, Pbca, a 18.144(5), b 15.952(5), c 7.494(2) A, Z 8, 1113 diffractometer reflections being refined by full matrix least squares to a residual of 0.052. The planar molecules of PdCl₂(bpy) are stacked into columns along the c direction, at a separation of c/2, neighbouring molecules in the stacks being related by glide planes with Pd…Pd separations of 4.587(2) A.
