Abstract

The structure of Fe(OH_0.86,OD_0.14)₂ was refined by applying the Rietveld technique to neutron powder diffraction data collected at 300, 150, and 10 K. The nuclear structure, of the CdI₂ type (P3 ml) and isostructural with Mg, Ça, Mn, Ni, and β-Co(OH)₂, is maintained over the range of temperatures studied. At 10 K, the magnetic structure is ordered antiferromagnetically, with the magnetic moments aligned in the basal plane. Thejefined Fe²⁺ magnetic moment magnitude is 3.50(4) μ_B. This magnetic structure (space group P_2c1̄) is unique amongst those encountered in the transition metal dihydroxides, for which the moment is either directed along the c axis |β-Co(OH)₂ and Ni(OH)₂], or at least has a considerable component along this direction [Mn(OH)₂]. The dependence of the strength of potential hydrogen bonds with temperature is discussed.
