title: Dirubidium digallium oxide bis-(ortho-borate).
abstract: The title compound, Rb(2)Ga(2)O(BO(3))(2), is part of the homologous series A(2)Ga(2)O(BO(3))(2) (A = Na, K, Rb and Cs). The structure contains pairs of gallium-centered tetra-hedra connected through a shared oxygen vertex. Orthoborate triangles connect the basal vertices of the tetra-hedra, forming a three-dimensional network with voids occupied by rubidium ions.
