Abstract: The asymmetric unit of the title complex [Cu(C14H12N2)2]2[Fe(CN)5(NO)], consists of a [Cu(dmp)2]+ cation (dmp is 2,9-dimethyl-1,10-phenanthroline) and half an [Fe(CN)5(NO)]2- anion. The anion is disordered across an inversion center with the FeII ion slightly offset (ca 0.205Å) from the inversion center in the direction of the disordered trans-coordinating CN/NO ligands. The anion has a distorted octahedral coordination geometry. The CuI ion is coordinated by two phenanthroline ligands in a distorted tetrahedral geometry. The dihedral angle between the phenanthroline ligands is 77.16 (4) Å. In the crystal, the cations are connected to the anions by weak C-HN hydrogen bonds. In addition, weak - stacking interactions are observed, with centroid-centroid distances in the range 3.512 (3)-3.859 (3) Å.
