[N,N,N',N'-Tetra-kis(benzimidazol-2-ylmeth-yl)cyclo-hexane-1,2-trans-diamine]-iron(II) bis-(perchlorate) methanol solvate.

In the title compound, [Fe(C(38)H(38)N(10))](ClO(4))(2)·CH(3)OH, the Fe(II) atom has a distorted octa-hedral coordination environment with four benzimidazol N atoms and two amino N atoms from an N,N,N',N'-tetra-kis-(benzimidazol-2-ylmeth-yl)cyclo-hexane-1,2-trans-diamine ligand. The uncoordinated solvent methanol mol-ecule is hydrogen bonded to an O atom of a perchlorate anion. One of the perchlorate anions is disordered over two sets of sites with occupancy factors of 0.539 (14) and 0.461 (14). N-H⋯O and C-H⋯O hydrogen bonds, as well as π-π stacking inter-actions between the imidazol rings and between the imidazol and benzene rings [centroid-centroid distances = 3.714 (2) and 3.705 (2) Å] give rise to a three-dimensional network.
