Abstract: In the crytal structure of the title compound, [Pd₂(C₅₆H₅₀N₈)]₂(BF₄)₄·8CH₃CN·H₂O, the asymmetric 5-phenyl-3-p-tolylpyrazolate ligands bridge (4,4'-dimethyl-2,2'-bipyridine-²N,N')palladium(II) units in cis and trans fashions, resulting in two coexistent dipalladium complexes. The six-membered rings consisting of the two Pd atoms and the four pyrazolyl N atoms have boat-shaped conformations in both independent complexes; the Pd atoms are four-coordinate in square-planar environments. The crystal structure is stabilized by electrostatic forces between the cations and anions, and weak intermolecular hydrogen bonds involving tetrafluridoborate anions (C-HF), the solvent acetonitrile molecules (C-HN) and water molecules (C-HO).
