(2,2'-Bipyridyl-N,N')dibromopalladium(II)

The title comlex, PdCl2(bipy), the 2,2'-bipyridine complex of palladium dichloride, has square-planar geometry for palladium with Pd-N 2.047(5) and Pd-Br 2.4102(9) Angstroms. The mean planes of the coordinated pyridine groups form a dihedral angle of 1.7(3) degrees with the coordination square plane; the parallel complexes stack with an interplanar spacing of 3.41(1) A and a Pd··Pd separation of 5.246(1) A to form a chain structure as reported for isomorphous PtI2(bipy) (where bipy is 2,2'-bipyridyl, C10H8N2). The structure differs from those found for related chain structures in the 'red' form of PtCl2(bipy) and in PdCl2(bipy) which is isomorphous with the 'yellow' form of PtCl2(bipy)
