摘要

Two new beryllium phosphites, H₂en路Be₃(HPO₃)₄ (1) and H₂pda路Be₃(HPO₃)₄ (2), have been synthesized under hydrothermal conditions. Single-crystal structural analyses reveal that both compounds have three-dimensional inorganic frameworks constructed from strictly alternating BeO₄ tetrahedra and HPO₃ pseudo pyramids. The structure of compound 1 can be described as a pillared layered structure with 12-ring channels. The structure of compound 2 has an interesting sqp topology if Be₃(HPO₃)₄ clusters are regarded as 5-connected nodes in the network.
