Abstract: 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 FeII 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...[pi] 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)°].
