Abstract
The structure of rubidium dilithium digallium tris(borate), RbLi2Ga2(BO3)3, contains two-dimensional sheets of open-branched rings of GaO4 tetrahedra and planar BO3 triangles that are joined by LiO4 tetrahedra to form a three-dimensional framework. Ten-coordinate Rb atoms lie on twofold axes and occupy channels within the framework that extend along the b axis.
