Abstract

The crystal structure of trilithium gallium bis-(orthoborate), Li₃Ga(BO₃)₂, is isotypic with Li₃Al(BO₃)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 tetra-hedra, and the two B atoms are coordinated by three O atoms in orthoborate triangles. Chains with composition [Ga₂(BO₃)₄]^6- extend along the a axis. The Li atoms inter-leave these chains in tetra-hedral inter-stices. 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. Khim. 13, 943-946.].
