Cis-Dichloro[tris(2-benzimidazolylmethyl)amine]iron(III) chloride ethanol dihydrate: hydrogen bonding changing the arrangement of tapes built from π–π and C—H...π interactions

Abstract

The title compound, [FeCl2(C24H21N7)]Cl.C2H5OH.2H2O, comprises an [FeCl2(C24H21N7)]+ cation, a Cl- anion, an ethanol molecule and two water molecules. The cations are linked by pi-pi and C-H...pi interactions into one-dimensional tapes, and hydrogen bonding between the cations, Cl- anions, and ethanol and water molecules links these tapes into a three-dimensional network.
