摘要：

Single crystals of LiFe3+(SeO3)2 were prepared by hydrothermal synthesis. The crystal structure of LiFe3+(SeO3)2 is reported: tetragonal, space group I42dBAR, a = 10.649(2) angstrom, c = 9.959(2) angstrom, V = 1129.4 angstrom3, Z = 8, 1268 unique reflections, R = 0.037. The structure contains LiFeO8 groups, built up by FeO6 octahedra edgesharing with strongly distorted LiO4 tetrahedra. These LiFeO8 groups share corners with trigonal pyramidal SeO3 groups to form a three dimensional network. The mean bondlengths are 1.994 angstrom, 2.006 angstrom and 1.699 A for Li-O, Fe-O and Se(IV)-O, respectively.
