(2,2'-BIPYRIDYL-N,N')DIBROMOPALLADIUM(II)

The title complex, [PdBr2(C10H8N2)], has square-planar geometry for pa lladium with Pd-N 2.047(5) and PdBr 2.4102(9)Angstrom. The mean planes of the coordinated pyridine groups form a dihedral angle of 1.7(3)deg rees with the coordination square plane; the parallel complexes stack with an interplanar spacing of 3.41(1)Angstrom and a Pd...Pd separatio n of 5.246(1)A to form a chain structure as reported for isomorphous P tI2(bipy) (where bipy is 2,2'-bipyridyl, C10H8N2). The structure diffe rs 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).
