摘要：

A single-crystal x-ray diffraction analysis has been performed on K5NdLi2F10 synthesized from a melt containing an excess of KF and LiF as a flux. The structure is orthorhombic with space group Pnma, Z = 4, and cell parameters a = 20.65, b = 7.779, c = 6.902 A ̊. A full-matrix least squares refinement gave R = 0.08 for 1056 independent reflections. The basic structural features are sheets, perpendicular to the a-axis, formed by isolated NdF8 dodecahedra and LiF4 tetrahedra. The sheets are held together by the K+ ions. The compound K5NdLi2F10 is the first reported fluoride in which the Nd polyhedra are isolated from each other. The shortest Nd-Nd distance is 6.72 Å, and the concentration of Nd3+ ions is 3.60 × 1021 cm-3. © 1979.
