Abstract

Rb4[B4O5(OH)4] 2·3H2O has been grown by slow evaporation method with crystal sizes up to 11 mm × 7 mm × 4 mm. Its crystal structure has been determined by single-crystal X-ray diffraction and further characterized by powder X-ray diffraction (XRD), IR, and TGA. It crystallizes in the orthorhombic space group Pbcn, with a = 16.3984(14) , b = 7.7850(7) , c = 16.0763(16) , and Z = 4. It contains isolated [B4O 5(OH)4]2- polyanions, free water molecules and Rb cations. The Rb(1) and Rb(2) atoms are coordinated by nine and ten oxygen atoms, respectively. Connections between isolated [B4O 5(OH)4]2- polyanions are provided by Rb polyhedra and the hydrogen-bonding to form a three-dimensional network.
