Abstract: In the crystal structure of the title compound, [Pd₂(C₂₂H₁₇N₂)₂(C₁₂H₁₂N₂)₂](PF₆)₂·C₄H₁₀O·H₂O, two Pd(dmbpy) units (dmbpy is 4,4'-dimethyl-2,2'-bipyridine) are bridged by 4-benzyl-3,5-diphenylpyrazolate ligands in an exodentate fashion, which results in a clip-like cavity between the two Pd(dmbpy)Pd planes. A disordered hexafluoridophosphate anion is held in the cavity by an anion- interaction [P-FCg1 = 3.435 (15) Å (Cg1 is the centroid of the Pd-dmbpy chelate ring system) and P-FCg2 = 3.187 (15) Å (Cg2 is the centroid of a pyridine ring)]. A crystallographic twofold rotation axis passes through an F atom of the disordered anion and the mid-point of the two Pd atoms. The P and two F atoms of the second anion also lie on a twofold rotation axis, as do the O atom of the diethyl ether and the water O atom. The crystal structure is stabilized by electrostatic forces between the cations and anions, and intermolecular hydrogen bonds involving hexafluoridophosphate anions (C-HF), the solvent diethyl ether molecules and water molecules (C-HO).
