Abstract
In the title complex, [Pd(C7H3NO4)(C13H9N)], the PdII 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) Å in dipic and 0.091 (4) Å in acr] and the dihedral angle between their mean planes is 58.67 (7)°. The Pd—O bond lengths are nearly equal, but the Pd—N bond lengths are slightly different. There is a short C—H⋯O interaction in the molecule involving the two ligands. In the crystal, complex molecules are linked through C—H⋯O interactions, forming a three-dimensional network. There are also a number of intermolecular π–π interactions present, the shortest ring centroid–centroid distance being 3.622 (3) Å.
