Abstract
Hexaaquanickel(II) chloro(hydrogenethylenediaminetetraacetato)ferrate(III), [Ni(H2O)6][FeCl(EDTA)H]2·4H2O, was prepared by the reaction of nickel(II) chloride with (hydrogenethylenediammine)iron(III) in water at room temperature. The compound readily loses water at room temperature depending on drying conditions and the relative humidity. The molecular structure of the dihydrate was determined by single-crystal X-ray crystallography. The compound decomposes in stages involving, successively, loss of water, pyrolysis of the EDTA ligand, and loss of HCl to yield, finally, stoichiometric nickel ferrite. Crystal data: C20H42N4O24Cl2Fe2Ni, M = 963.88, monoclinic, space group P21/c, a = 20.548(3) A, b = 7.401(1) A, c = 12.827(1) A, β = 101.78(1)°, V = 1909.6(7) A3, Z = 2, Dcalc = 1.68 g cm-3, R = 0.028, and Rw = 0.040.
