摘要

The first FeIII atom in the solvated title compound, Fe2Cl4O(C26H28N4)#183;CHCl3, adopts a distorted six-coordinate octa#173;hedral geometry. It is coordinated by one chloride ligand, four N atoms from the (1R,2R)-N,N#8242;-bis#173;(quinolin-2-yl)methylcyclo#173;hexane-1,2-di#173;amine ligand, and a bridging oxido ligand attached to the second FeIII atom, which is also bonded to three chloride ions. A very weak intra#173;molecular N#8212;H#8943;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 chloro#173;form solvent mol#173;ecules. Although the Fe#8212;Cl bond lengths for the two metal atoms are comparable to the mean Fe#8212;Cl bond lengths as derived from the Cambridge Structural Database, the Fe#8212;O bond lengths are notably shorter. The solvent chloro#173;form mol#173;ecule exhibits `flip' disorder of the C#8212;H moiety in a 0.544#8197;(3):0.456#8197;(3) ratio. The only directional inter#173;action noted is a weak C#8212;H#8943;Cl hydrogen bond.
