Description |
Three neutral bis(mu-chalcogenido) diiron(III) complexes, [{(N, N'-Pipiso) Fe(mu-E)}(2)] (Pipiso-= [(DipN)(2)C(cis-2,6-Me2NC5H8)](-), (Dip = C6H3Pr2i-2,6; E = O, S or Se) have been prepared by reactions of the iron(I) dimer [{(mu-N, N'-Pipiso)Fe}(2)] with O-2, S-8 or Se-infinity. Treating the mu-selenido compound [{(N, N'-Pipiso) Fe( mu-Se)}(2)] with O-2 cleanly generated its mu-oxo counterpart, [{(N, N'-Pipiso) Fe(mu-O)}(2)]. X-ray crystallographic analyses of the compounds showed them to possess Fe-2(mu-E)(2) core structures with distorted square planar (E = O) or tetrahedral (E = S or Se) iron coordination geometries. Magnetic, Fe-57 Mossbauer spectroscopic and computational studies indicate medium to strong antiferromagnetic coupling between the two high-spin Fe-III ions in all three compounds.
