Crystal structure of trinuclear, Oxo-centered base carboxylate, Fe(III) complex containing DMSO ligand and anion of Fe2Cl6O

Abstract

The crystal structure of [Fe3O(OAc)6(DMSO)3]2+·(Fe2Cl6O)2- was determined by the X-ray diffraction method. This complex crystallized in the triclinic system, space group P 1, with two molecules per unit cell. The unit-cell dimensions are a = 9.9509(7)Å, b = 14.0228(10)Å, c = 15.0561(11)Å, α = 108.7700(10)°, β = 100.6800(10)°, γ = 105.7890(10)° and V = 1826.3(2)Å. The final R value is 0.0371 for 8369 measured reflections. In the cationic section of this complex the coordination sphere around each metal center is close to a distorted octahedral. Every two irons are connected to each other, by two bridges of alkyl acetate. The DMSO molecule as a monodentate ligand is connected to every iron. Anionic section has a trigonal antiprism skeleton that the oxygen atom lies in the center of these structures. 2006 © The Japan Society for Analytical Chemistry.
