title: Bis(2,2'-bipyrimidine-κ(2)N(1),N(1'))palladium(II) bis-(tetra-fluoro-borate) acetonitrile monosolvate.
abstract: The reaction of [Pd(MeCN)(4)](BF(4))(2) with 2,2'-bipyrimidine (bpm) in MeCN-CHCl(3) afforded the title compound, [Pd(C(8)H(6)N(4))(2)](BF(4))(2)·C(2)H(3)N. The asymmetric unit contains two half complexes, with the Pd(II) atoms both lying on a twofold axis. Each metal atom adopts a tetra-hedrally 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 inter-actions involving the tetra-fluoro-borate anions and acetonitrile mol-ecules. In this way, each chain interacts with six surrounding chains to generate the observed three-dimensional structure.
