Synthesis, Crystal Structure and Magnetic Property of Diiron Complex [Fe(phen)₃][Fe₂OCl₆]·2CH₃CN

Abstract

A new diiron complex has been synthesized and characterized by X-ray single crystal structural analysis: [Fe n (phen)3] [Fe IH 20Cl6] -2CH3CN. The complex crystallizes in the monoclinic system, space group C2/c, with lattice parameters a = 21.162(4) Ä, b = 15.168(3) Ä, c = 14.812(3) Ä, ß = 112.71 (3)°, V = 4385.8(15) Ä 3 , Dx = 1.543 Mg/m 3 , Z = 4. The corresponding variable temperature susceptibility measurement shows that there ex ists an antiferromagnetic interaction in the complex.

Tris(1,10-phenanthroline)iron(II) μ-oxido-bis[trichloridoferrate(III)]

“…Previously, many efforts have been contributed to these researches, especially to the models for non-heme metalloproteins (Davydov et al, 1997;Mauerer et al, 1993;Ito et al, 1996;Okuno et al, 1997;Menage et al, 1993). Here, we report a ionic compound, [Fe(phen) octahedron, Fe-N bond lengths range from 1.972 (4) Å to 1.985 (4) Å and are similar to those reported in the literature (Yan et al, 2000;Li et al, 2008). In the anionic group two Fe III cations locate in similar tetrahedral environments constructed by three Cland one µ 2 -bridged O 2ligand.…”

“…Fe complexes containing phen have been studied for their ability to interact with DNA (Furtado et al, 1997;Mudasir et al, 2003). Few crystal structures of Fe 3+ complexes of phen have been reported (Baker et al, 1975), although there are many papers describing crystal structures containing [Fe(phen)] 2+ cations (Broomhead et al, 1982;Che et al, 1997;Deng et al, 2001;Hoshina et al, 2000;Koh et al, 1994;Li et al, 1993;Reiff et al, 1983;Ronco et al, 1986;Yan et al, 2000;Zalkin et al, 1973). In the present study, we synthesized the title compound, [Fe(phen) 3 ] 3+ Á3NO 3 À ÁH 2 O, and analyzed its crystal structure.…”
