[N,N,N′,N′-Tetrakis(benzimidazol-2-ylmethyl)cyclohexane-1,2-trans-diamine]iron(II) bis(perchlorate) methanol solvate
Abstract
In the title compound, [Fe(C38H38N10)](ClO4)2·CH3OH, the FeII atom has a distorted octahedral coordination environment with four benzimidazol N atoms and two amino N atoms from an N,N,N′,N′-tetrakis(benzimidazol-2-ylmethyl)cyclohexane-1,2-trans-diamine ligand. The uncoordinated solvent methanol molecule 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 interactions 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.
