title: (2,9-Dimethyl-1,10-phenanthroline-κN,N')(4-hydroxy-benzoato-κO,O')(nitrato-κO)copper(II).
abstract: In the title compound, [Cu(C(7)H(5)O(3))(NO(3))(C(14)H(12)N(2))], the Cu(II) ion is five-coordinated in a slightly distorted square-pyramidal geometry by one O atom of a nitrate anion, two O atoms of a 4-hydroxy-benzoate anion, and two N atoms from a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand. In the crystal structure, inversion-related mol-ecules are linked into dimers by O-H⋯O hydrogen bonds. The packing is further stabilized by π-π inter-actions involving the benzene rings of the dmphen and hydroxy-benzoate units, with centroid-centroid distances of 3.4930 (14) or 3.5727 (14) Å.
