title: A new monoclinic polymorph of trans-dichloridodipyridine-palladium(II).
abstract: In the structure of the title compound, [PdCl(2)(C(5)H(5)N)(2)], the Pd(II) atom is located on an inversion centre and the pyridine rings are coplanar. There is inter-molecular π-π stacking between the pyridyl rings, with a centroid-to-centroid separation of 3.916 (1) Å. The structure is a new polymorph of two previously determined structures [Viossat, Dung & Robert (1993 ▶). Acta Cryst. C49, 84-85; Liao & Lee (2006 ▶). Acta Cryst. E62, m680-m681].
