A novel mixed octahedral–tetrahedral framework: X-ray characterization of a microporous gallophosphate, Ga2P2O8(OH)H2O·NH4·H2O·0.16 PrOH (GaPO4-C7)

Abstract
The structure of the microporous gallophosphate, Ga2P2O8(OH)H2O·NH 4·H2O·0.16 PrOH, consists of gallium-centred octahedra and phosphorus-centred tetrahedra as basic building units to form three-dimensional channels with the 8-ring running along the a,b, and c axes in which NH4+ cations are located in pairs.
