Synthesis, crystal structures and optical properties of open-framework gallium phosphates: NaGa3F4(PO4)(2)(H2O)(2) and AGa(2)P(2)O(7)(OH)(3)(H2O) (A = K, Rb)

Wang, Tianyou; Wu, Chao; Lin, Lin; Huang, Zhipeng; Humphrey, Mark; Zhang, Chi


Three new alkali-metal gallium phosphates NaGa3(PO4)2F4(H2O)2 (1), KGa2P2O7(OH)3(H2O) (2), and RbGa2P2O7(OH)3(H2O) (3) were obtained using hydrothermal methods. Compound 1 crystallizes in the chiral space group P43212. The structure of 1 features a three-dimensional (3D) framework composed of 2D layers of corner-sharing GaO4F2 and GaO2F4 octahedra that are further bridged by PO4 tetrahedra with Na+ cations residing in the oxyfluorinated gallolayers. Compounds 2 and 3 are isostructural, both...[Show more]
