cis-(2,2′-Bipyridine-κ²N,N′)bis­(isonicotinamide-κN¹)palladium(II) bis­(hexa­fluoridophosphate)

In the title salt, [Pd(C₁₀H₈N₂)(C₆H₆NO)₂](PF₆)₂, the Pd^II atom is in a slightly distorted square-planar coordination environment by N atoms derived from two 4-pyridine­carboxamide ligands, in a cis disposition, and a chelating 2,2′-bipyridine mol­ecule. The monodentate ligands are nearly orthogonal to each other [dihedral angle = 85.7 (5)°] and to the PdN₄ plane [dihedral angles = 79.3 (3) and 78.7 (3)°]. The amide O atoms lie to opposite sides of the PdN₄ plane. The most notable feature of the crystal packing is a linear supra­molecular chain orientated approximately along [310] and formed via 16-membered {...HNCO}₄ motifs. These are connected into a three-dimensional network by amide–H...O, F inter­actions. Both PF₆⁻ anions are disordered over two positions of equal occupancy in respect of the F atoms.
