Chloro[N,N′-ethylenebis(5-carboxysalicylidene-iminato)]iron(III)

In the title compound, [FeCl(C18H14N2O6)], the iron(III) is coordinated by N and O atoms at the basal sites and Cl at the apical site to form a distorted square pyramid. Hydrogen bonding in carboxylic acid dimers and pi-pi stacking interactions through benzene rings of the ligand lead to paired chains, which are alternately crosslinked with each other to form a non-porous solid. The title compound is potentially a good building block for the construction of highly porous mixed-metal-organic frameworks (M'MOFs). The O ... O distances in the carboxylic acid dimers are 2.555 (6) and 2.664 (6) Angstrom.
