(Acridine-kappa N)(pyridine-2,6-dicarboxylato-kappa O-3(2),N,O-6)palladium(II)

In the title complex, [Pd(C7H3NO4)(C13H9N)], the Pd-II ion is four-coordinated in a distorted square-planar environment by one N and two O atoms from the tridentate pyridine-2,6-dicarboxylate (dipic) anionic ligand and one N atom of the acridine (acr) ligand. The dipic and acr ligands are nearly planar [maximum deviation = 0.069 (3) angstrom in dipic and 0.091 (4) angstrom in acr] and the dihedral angle between their mean planes is 58.67 (7)degrees. The Pd-O bond lengths are nearly equal, but the Pd-N bond lengths are slightly different. There is a short C-H center dot center dot center dot O interaction in the molecule involving the two ligands. In the crystal, complex molecules are linked through C-H center dot center dot center dot O interactions, forming a three-dimensional network. There are also a number of intermolecular pi-pi interactions present, the shortest ring centroid-centroid distance being 3.622 (3) angstrom.
