Abstract

The first FeIII atom in the solvated title compound, [Fe2Cl4O(C26H28N4)]·CHCl3, adopts a distorted six-coordinate octahedral geometry. It is coordinated by one chloride ligand, four N atoms from the (1R,2R)-N,N′-bis[(quinolin-2-yl)methyl]cyclo hexane-1,2-diamine ligand, and a bridging oxido ligand attached to the second FeIII atom, which is also bonded to three chloride ions. A very weak intramolecular N-H·Cl hydrogen bond occurs. In the crystal, the coordination complexes stack in columns, and a grouping of six such columns create channels, which are populated by disordered chloroform solvent molecules. Although the Fe-Cl bond lengths for the two metal atoms are comparable to the mean Fe-Cl bond lengths as derived from the Cambridge Structural Database, the Fe-O bond lengths are notably shorter. The solvent chloroform molecule exhibits 'flip' disorder of the C-H moiety in a 0.544(3):0.456 (3) ratio. The only directional interaction noted is a weak C-H·Cl hydrogen bond.
