Two identical [FeLCl] [L = N-(4-chloro-2-hydroxyphenyl)-3-hydroxy-2-naphthaldimine] fragments, related by an inversion centre, are combined by the two bridging O atoms, forming a binuclear unit, dichlorobis-mu-{1-[4-chloro-(2-oxido-1:2kappa2O')-phenyliminomethyl]naphalen 2-olato}-1kappa2N,O;2kappa2N,O-diiron(III). The two iron(III) centres are 3.186 (4) angstrom apart and the distance between the two bridging O atoms amounts to 2.417 (8) angstrom. The two Fe-O distances [Fe-O(2) and Fe-O(2A)] are different [2.047 (8) and 1.951 (8) angstrom, respectively]. The Fe-O(2)-Fe(A) angle in the central four-membered ring is 105.64 (4)degrees.
