Tetra-kis(pyridine-2-carboxyl-ato-κN,O)palladium(IV) dihydrate.

ABSTRACT: The asymmetric unit of the title compound, [Pd(C(6)H(4)NO(2))(4)]·2H(2)O, consists of a quarter of a neutral Pd(IV) complex and half of a solvent water mol-ecule. In the complex, the Pd(IV) ion is located on a fourfold inversion axis and eight-coordinated in a distorted dodeca-hedral environment by four N and four O atoms from four symmetry-related pyridine-2-carboxyl-ate (pic) anionic ligands. In the crystal, the water mol-ecule is involved in O-H⋯O hydrogen bonding, and weak inter-molecular C-H⋯O hydrogen bonds occur. There are also inter-molecular π-π inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.715 (3) Å.
