Lutetium(III) cyclotetraphosphate

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 AlIII and ScIII analogues and is built up from four-membered (P4O12)4− phosphate ring anions ( 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.
