cis-(2,2 '-Bipyridine-kappa N-2,N ') bis(isonicotinamide-kappa N-1)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)degrees] and to the PdN4 plane [dihedral angles = 79.3 (3) and 78.7 (3)degrees]. 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 {center dot center dot center dot HNCO}(4) motifs. These are connected into a three-dimensional network by amide-H center dot center dot center dot O, F interactions. Both PF6- anions are disordered over two positions of equal occupancy in respect of the F atoms.
