Single crystals of the title compound, tetra-lutetium(III) tris-(cyclo-tetra-phosphate), Lu(4)(P(4)O(12))(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 (P(4)O(12))(4-) phosphate ring anions ( symmetry), isolated from each other and further linked through isolated LuO(6) octa-hedra (.3. symmetry) via corner sharing. Each LuO(6) octa-hedron is linked to six (P(4)O(12))(4-) rings, while each (P(4)O(12))(4-) ring is linked to eight LuO(6) octa-hedra.
通过固态反应获得了标题化合物四镥（III）三（环四磷酸盐），即Lu₄(P₄O₁₂)₃的单晶。其立方结构与其铝（III）和钪（III）类似物同型，由四元（P₄O₁₂）⁴⁻磷酸环阴离子（对称）构成，这些阴离子彼此分离，并通过孤立的LuO₆八面体（.3.对称）通过角共享进一步连接。每个LuO₆八面体与六个（P₄O₁₂）⁴⁻环相连，而每个（P₄O₁₂）⁴⁻环与八个LuO₆八面体相连。
