The asymmetric unit of the title compound, [Fe(C10H8N2)3][C{C(CN)2}3], contains an iron–bipyridyl unit and one third of two crystallographic independent tris(dicyanomethylidene)methanediide units. In the crystal, hydrogen bonds between cations and anions form complex layers parallel to (001). These are supplemented by hydrogen bonds perpendicular to the former, leading to a three-dimensional network.
