Abstract
Abstract A new sodium hydroxygallophosphate, Na 3 Ga 4 O(OH)(H 2 O)(PO 4 ) 4 ·H 2 O, has been prepared by hydrothermal synthesis. Its structure has been determined from a single-crystal X-ray diffraction study. It crystallizes in the P 2 1 / c space group with the cell parameters a =9.445(2) A, b =9.028(1) A, c =19.209(3) A, β =102.08(2), V =1603.4(4) A 3 . Its three-dimensional framework can be described from PO 4 monophosphate groups sharing their apices with original Ga 4 O 16 (OH)(H 2 O) tetrameric building units, which result from the assembly of one GaO 4 tetrahedron, one GaO 5 trigonal bipyramid and two octahedra: GaO 5 (OH) and GaO 4 (OH)(H 2 O). The sodium cations and one water molecule are located in tunnels running along b .
