Two new beryllium phosphites, H(2)en center dot Be-3(HPO3)(4) (1) and H(2)pda center dot Be-3(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 Beat tetrahedra and HPO3 pseudo pyramids. The structure of compound I can be described as a pillared layered structure with 12-ring channels. The structure of compound 2 has an interesting sqp topology if Be-3(HPO3)(4) clusters are regarded as 5-connected nodes in the network.
