Abstract: The asymmetric unit of the title compound, tetrakis[8-methylphenanthridin-6(5 H )-one-κ O ]bis(nitrato-κ O )copper(II), [Cu(NO 3 ) 2 (C 14 H 11 NO) 4 ], contains one Cu II cation located on a centre of symmetry, two 8-methylphenanthridin-6(5 H )-one (MPHNT) ligands and one nitrate anion, where the Cu II atom is in a slightly distorted octahedral environment. Intramolecular N—H...O hydrogen bonds are observed. In the crystal, C—H...O hydrogen bonds link the molecules, enclosing S(6), S(9) and R 4 4 (18) ring motifs. In addition π–π interactions with centroid-to-centroid distances of 3.808 (2) Å and also a series of C—H...π(ring) interactions help to consolidate the packing in a three-dimensional architecture within the crystal. A Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H...H (41.1%), H...C/C...H (29.9%), H...O/O...H (14.8%) and C...C (10.0%) interactions.
