Abstract: The title compound, [Cu(CN)(C12H8N2)2]2[Fe(CN)5(NO)]·C3H7NO, is formed of discrete [Cu(phen)2CN]+ cations (phen is 1,10-phenanthroline), nitroprusside [Fe(CN)5(NO)]2- anions and dimethylformamide (DMF) molecules of crystallization. The metal atom has a distorted trigonal-bipyramidal coordination environment, defined by four N atoms of two phen molecules and a C atom of the cyanide group (in the equatorial position). The [Fe(CN)5(NO)]2- anion was found to be disordered about (but not on) a crystallographic twofold rotation axis. Geometries were restrained to ideal values. The dimethylformamide solvent molecule was found to be disordered about a crystallographic inversion centre.
