Cis-Bis(-5-phenyl-3-p-tolyl-pyrazolato-² N:N′)bis-[(4, 4′-dimethyl-2,2′-bipyridine-² N,N′)palla-dium(II)] trans-bis-(-5-phenyl-3-p-tolyl-pyrazolato-² N:N′)bis-[(4, 4′-dimethyl-2,2′-bipyridine-² N,N′)-palladium(II)] tetra-kis(tetra-fluoridoborate) acetonitrile octa-solvate monohydrate

In the crytal structure of the title compound, [Pd2(C56H50N8)]2(BF4) 4·8CH3CN·H2O, the asymmetric 5-phenyl-3-p-tolyl-pyrazolate ligands bridge (4,4′-dimethyl-2,2′-bipyridine-² N,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 inter-molecular hydrogen bonds involving tetraflurido-borate anions (C - H⋯F), the solvent acetonitrile mol-ecules (C - H⋯N) and water mol-ecules (C - H⋯O).
