Crystal structure of ({(1R,2R)-N,N′-bis­[(quino­lin-2-yl)methyl]cyclo­hexane-1,2-di­amine}­chlorido­iron(III))-μ-oxido-[tri­chlorido­ferrate(III)] chloro­form monosolvate

The first Fe(III) atom in the solvated title compound, [Fe(2)Cl(4)O(C(26)H(28)N(4))]·CHCl(3), 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]cyclo­hexane-1,2-di­amine ligand, and a bridging oxido ligand attached to the second Fe(III) 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.
