| Abstract: | Employing diethylenetriamine (=dien) as a structure-directing agent, a new open-framework beryllium phosphite H2dien·Be3(HPO3)4 (1), has been synthesized hydrothermally and structurally characterized by single crystal X-ray diffraction. The structure of 1 features a (3, 4)-connected framework with 8- and 12-ring channels, which is constructed from strictly alternating BeO4 tetrahedra and HPO32− pseudopyramids. The 3-D framework possesses a pcu topology when the heptameric Be3(HPO3)4] clusters are regarded as 6-connected secondary building units. Crystal data: 1, monoclinic, C2/c (no. 15), a = 8.7350(3) Å, b = 15.1704(6) Å, c = 13.0851(4) Å, β = 101.223(5)°, V = 1700.79(10) Å3, Z = 4, R1 = 0.0625, wR2 = 0.1692. |
