Crystal structure of Li₃Ga(BO₃)₂

Abstract

The crystal structure of trilithium gallium bis(orthoborate), Li 3 Ga(BO 3 ) 2 , is isotypic with Li 3 Al(BO 3 ) 2 in a triclinic cell in space-group type P -1. The three Li and the unique Ga atom are coordinated by four O atoms each in tetrahedra, and the two B atoms are coordinated by three O atoms in orthoborate triangles. Chains with composition [Ga 2 (BO 3 ) 4 ] 6− extend along the a axis. The Li atoms interleave these chains in tetrahedral interstices. A comparison is made between the structure model of the title compound and that of a previously reported model for a compound with the same composition [Abdullaev & Mamedov (1972). Zh. Strukt.
