Using 1,3-propanediamine as a template, two one-dimensional phosphate microporous molecular sieves were synthesized under solvothermal conditions: [GaP 2 O 7 (OH)] [NH 3 (CH 2) 3 NH 3] The structure of X-ray single crystals shows that the two crystal structures are composed of gallium oxytetrafluoroethylene tetrahedron and phosphooxy tetrahedron, or gallium oxytetrafluoro tetrahedron, Germanium oxy tetrahedron and phospho-tetrahedron and form a chain along the c-axis of the layer.These chains are connected by 1,3-propanediamine.The crystallographic data of 1 are Mr = 3 3 1 82, P 1, a = 0 83 0 3 (2) nm, b = 0 8614 (3) nm, c = 0 8880 (2) nm, 98 3 9 (2) °, V = 0 5 3 82 (3) nm3, Z = 1, MoKα, λ = 0 0 710 73nm, R (F) = 556%, wR (F2) = 14 3 6 The crystallographic data for% .2 are: P2 (1) / c, a = 0 88968 (7) nm, b = 1 675 62 (13) nm, c = 0 83 666 (7) nm, 2), V = 1 12 2 0 8 (16) nm3, Z = 4, MoKα, R (F) = 4 66%, wR (F2) = 10 10%.
