Abstract
Two Cr-III-Fe-III complexes, K-2[Cr(salen)(H2O)][Fe(CN)(6)].H2O (1) and [tr ans-Cr(tn)(2)Cl-2](3)[Fe(CN)(6)]. 6H(2)O (2), have been prepared. Crystal s tructure determination shows that complex (2) possesses an ionic salt struc ture. General physical measurements and magnetic studies indicate that (1) assumes a cyanide-bridged dinuclear structure, and that the Cr-III-Fe-III m agnetic coupling through the cyanide bridge is antiferromagnetic, which can be rationalized by the overlap of magnetic orbitals of the same symmetry.
