An organically templated beryllophosphite, [H₃N(CH₂)₃NH₃]·[Be₃(HPO₃)₄] 1, has been synthesizedunder mild hydrothermal conditions and characterized by single-crystal X-ray diffraction. It is the first beryllophosphite using organic amine as a structure-direction agent. Compound 1 crystallizes in a monoclinic system,space group P2₁/c with cell parameters: a = 8.5983(15) Å, b = 13.1561(19) Å, c = 13.460(2) Å, = 92.470(5), andZ = 4. The three-dimensional framework is built up from strictly alternating BeO₄ tetrahedra and [HPO₃^2-]pseudopyramid by sharing vertices. A new type of network containing 4-, 6-, 8-, 10-, 12-membered rings makes upthe inorganic framework. The 1,3-diammonium propane template molecules are located in 8-membered ring windows.The compound was characterized by IR spectroscopy, inductively coupled plasma (ICP), and differential thermaland thermogravimetric analyses.
