title: Bis[chloridobis(1,10-phenanthroline)copper(II)] penta-cyanido-nitro-soferrate(II) di-methyl-formamide monosolvate.
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 di-methyl-formamide (DMF) solvent mol-ecule of crystallization per asymmetric unit. The Cu(II) 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 nitro-prusside counter-anion with the Fe(II) atom located on an inversion center with a slightly distorted octa-hedral 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 inter-actions are observed with centroid-centroid distances in the range 3.565 (2)-3.760 (3)Å. The di-methyl-formamide solvent mol-ecule was refined as disordered about an inversion center.
