Lutetium(III) cyclotetraphosphate

A. Mbarek, M. Fourati, D. Zambon and D. Avignant

Abstract: Single crystals of the title compound, tetralutetium(III) tris(cyclotetraphosphate), Lu₄(P₄O₁₂)₃, were obtained by solid-state reaction. The cubic structure is isotypic with its Al^III and Sc^III analogues and is built up from four-membered (P₄O₁₂)^4- phosphate ring anions ( $\\overline{4}$ symmetry), isolated from each other and further linked through isolated LuO₆ octahedra (.3. symmetry) via corner sharing. Each LuO₆ octahedron is linked to six (P₄O₁₂)^4- rings, while each (P₄O₁₂)^4- ring is linked to eight LuO₆ octahedra.
