摘要：

Ca8[Ga2SiO6]4(OH)8 is the first gallosilicate containing Ga‐O‐Ga links. The gallium‐rich compound crystallizes in a sodalite structure, in which the number of Ga‐O‐Ga links is minimized, according to Löwenstein's rule, by surrounding each SiO4 tetrahedron by four GaO4 tetrahedra. The hydroxide ions present in the sodalite cage are disordered and form weak hydrogen bonds with the framework oxygen atoms (depicted on the right). (Figure Presented.)
