Abstract

The title complex [CuCl(C12H8N2)2]2[Fe(CN)5(NO)]·C3H7NO, consists of discrete [Cu(phen)2Cl]+ cations (phen is 1,10-phenanthroline), [Fe(CN)5NO]2− anions and one dimethylformamide (DMF) solvent molecule of crystallization per asymmetric unit. The CuII atom is coordinated by two phenanthroline ligands and one chloride ion in a distorted trigonal–bipyramidal geometry. The dihedral angle between the phen ligands is 77.92 (7)°. The cation charge is balanced by a disordered nitroprusside counter-anion with the FeII atom located on an inversion center with a slightly distorted octahedral coordination geometry. In the crystal, weak C—H⋯N and C—H⋯Cl hydrogen bonds connect anions and cations into a two-dimensional network parallel to (100). In addition, π–π stacking interactions are observed with centroid–centroid distances in the range 3.565 (2)–3.760 (3)Å. The dimethylformamide solvent molecule was refined as disordered about an inversion center.
