Tris(5,6-dimethyl-1,10-phenanthroline-κ²N,N′)iron(II) bis­(tricyano­methanide)

The title compound, [Fe(C₁₄H₁₂N₂)₃](C₄N₃)₂, consists of one [Fe(dimephen)₃]²⁺ complex cation (dimephen = 5,6-dimethyl-1,10-phenanthroline) and two uncoordinating tcm anions (tcm = tricyano­methanide). In the complex cation, the Fe^II atom is coordinated by six N atoms from three chelating dimephen ligands at an average Fe—N distance of 1.963 (4) Å giving a distorted octa­hedral geometry. The crystal structure is stabilized by weak C—H...N hydrogen bonds and C[triple bond]N...π inter­actions between planar [maximum deviations of 0.024 (3) and 0.015 (3) Å] tcm anions and pyridine rings of dimephen [N2...centroid = 3.531 (3) and 3.726 (3) Å; C[triple bond]N...centroid = 96.4 (2) and 97.1 (2)°].
