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, [pi]-[pi] 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.
