In the ionic structure of the title compound the octahedral tris-chelate [Fe(phen)3]2+ dications afford one-dimensional chains by a series of slipped pi-pi stacking interactions [centroid-to-centroid distances = 3.792 (3) and 3.939 (3) Å]. The anions, denoted tcnoetOH- reveal an appreciable delocalization of pi-electron density. This is also supported by density functional theory (DFT) calculations. The double anion . . . π interaction involving a nitrile group of tcnoetOH- and two cis-positioned pyridine rings suggest the relevance of anion. . . π stackings for charge-diffuse polycyanoanions and common M-chelate species.
