A 2ND POLYMORPH OF 2,2'-BIPYRIDYL(METHYL)(PHENYL)PALLADIUM(II)

The crystal structure of a second polymorph of [Pd(CH3)(C6H5)(C10H8N2) ], containing four crystallographically independent molecules, is pres ented and compared with the structure of the previously reported polym orph [Markies et al. (1994). J. Organomet. Chem. 482, 191-199] contain ing only one crystallographically independent molecule. In both polymo rphs molecules lie in infinite stacks, surrounded by six similar stack s; the main difference between the two polymorphs is about 23 degrees in the tilt angle of the coordination plane with reference to the stac king direction.
