Abstract

The title compound, Li(3.5)Eu(1.5)(MoO(4))(4), was prepared by solid-state reactions. The fundamental building units of the structure are LiO(4) polyhedra (site symmetry [Formula: see text]), distorted LiO(6) polyhedra and MoO(4) tetra-hedra, which are further inter-connected via corner-sharing O atoms. One site is occupied by both Li and Eu atoms in a substituent disordered manner (0.25:0.75), and the Li/Eu atoms are coordinated by eight O atoms in a distorted square-antiprismatic manner.

摘要

标题化合物Li(3.5)Eu(1.5)(MoO(4))(4)通过固相反应制备。该结构的基本构筑单元是LiO(4)多面体(点群对称性[化学式:见原文])、扭曲的LiO(6)多面体和MoO(4)四面体,它们通过共用角顶的O原子进一步相互连接。一个位点被Li和Eu原子以取代无序的方式(0.25:0.75)占据,且Li/Eu原子以扭曲的四方反棱柱方式由八个O原子配位。
