Title: Synthesis and characterization of a new open-framework aluminophosphate C4N3H16·Al4P5O20(H2O)2 (AlPO-CJ31)
Abstract: A new three-dimensional (3-D) open-framework aluminophosphate (denoted AlPO-CJ31), with an Al/P ratio of 4/5, has been synthesized hydrothermally in the presence of diethylenetriamine (DETA) as the structure-directing agent (SDA). Its structure is determined by single-crystal X-ray diffraction and further characterized by X-ray powder diffraction, ICP, TG analyses and solid-state NMR techniques. The alternation of AlO4 tetrahedra, AlO5(H2O) octahedra and PO4 tetrahedra gives rise to an interrupted open-framework structure with parallel 8-membered ring (MR) and 12-membered ring channels along the [0 0 1] directions. Crystal data: C4N3H16 · Al4P5O20(H2O)2, orthorhombic Pbcn (No. 60), a = 24.7293(16) Å, b = 8.9442(4) Å, c = 9.9806(5) Å, V = 2207.5(2) Å3, Z = 4, R1 = 0.0720 (I > 2σ(I)), and wR2 = 0.1669 (all data).
