title: A new orthoborate, Sr3Ga3(BO3)4O(OH)
abstract: The crystal structure of tristrontium trigallium tetraborate oxide hydroxide has been determined by X-ray diffraction using a crystal grown by hydrothermal crystallization of a strontium gallo-borate glass. It represents a new orthoborate structure type built of complex layers formed by BO(3) triangles sharing corners with Ga(2)O(7) tetrahedral dimers and GaO(4)OH square pyramids. The Sr atoms occupy both inter- and intralayer sites.
