Synthesis, crystal structure and Hirshfeld surface analysis of [Cu(NO <sub>3</sub> ) <sub>2</sub> {8-methylphenanthridin-6(5 <i>H</i> )-one} <sub>4</sub> ]
The asymmetric unit of the title compound, tetra-kis-[8-methyl-phenanthridin-6(5<i>H</i>)-one-κ<i>O</i>]bis-(nitrato-κ<i>O</i>)copper(II), [Cu(NO<sub>3</sub>)<sub>2</sub>(C<sub>14</sub>H<sub>11</sub>NO)<sub>4</sub>], contains one Cu<sup>II</sup> cation located on a centre of symmetry, two 8-methyl-phenanthridin-6(5<i>H</i>)-one (MPHNT) ligands and one nitrate anion, where the Cu<sup>II</sup> atom is in a slightly distorted octa-hedral environment. Intra-molecular N-H⋯O hydrogen bonds are observed. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules, enclosing S(6), S(9) and <i>R</i> <sup>4</sup> <sub>4</sub>(18) ring motifs. In addition π-π inter-actions with centroid-to-centroid distances of 3.808 (2) Å and also a series of C-H⋯π(ring) inter-actions 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%) inter-actions.
