The reaction of [Pd(MeCN)4](BF4)2 with 2,2'-bipyrimidine (bpm) in MeCN-CHCl3 afforded the title compound, [Pd(C8H6N4)2](BF4)2·C2H3N. The asymmetric unit contains two half complexes, with the PdII atoms both lying on a twofold axis. Each metal atom adopts a tetrahedrally distorted square-planar geometry. In the crystal, [Pd(bpm)2] dications are linked by C-H...N hydrogen bonds, forming chains parallel to the b axis. The chains are further linked by C-H...F and C-H...N interactions involving the tetrafluoroborate anions and acetonitrile molecules. In this way, each chain interacts with six surrounding chains to generate the observed three-dimensional structure.

Similar Pd(bpm)2 complexes are unknown, but the subject of related dicationic adducts of PdII with 2,2'-bipyridyl (bpy) has been reviewed by Constable (1989[Constable, E. C. (1989). Adv. Inorg.
