Sammlung: WebWe investigate the correct structure of tavorite LiFeSO 4 F, which was newly determined. The concentration of intrinsic defects in the tavorite form is very low in comparison with the triplite form. Configurations of FeO 4 F 2 octahedra in the triplite form are in favor of corner-sharing connections over edge-sharing ones. WebPure tavorite LiFePO 4 (OH) was synthesized through a hydrothermal route. A fine structural analysis was done by X-ray and neutron diffraction techniques. The structure consists of a three-dimensional network with iron(III) octahedra (FeO 6) sharing corners, forming chains that run along the b direction. These chains are interconnected by PO 4 … roth distribution rules for beneficiaries
