Tris(1,10-phenanthroline-κ2N,N′)iron(II) bis(1,1-dicyano-2-ethoxy-2-oxoethanide)

Abstract

The title compound, [Fe(C12H8N2)3](C6H5N2O2)2, consists of one [Fe(phen)3]2+ cation (phen = 1,10-phenanthroline) and two 1,1-dicyano-2-ethoxy-2-oxoethanide anions. Five atoms of the anion are disordered over two positions [site occupancy = 0.521 (13) for the major component]. In the complex cation, the FeII atom is coordinated by six N atoms from three phen ligands in a distorted octahedral geometry. Two intramolecular C—H...N hydrogen bonds occur in the complex cation. The crystal structure is mainly stabilized by Coulombic interactions. Weak intermolecular C—H...N interactions are also observed.
