Hydrothermal synthesis and characterization of two organically templated cadmium borophosphates with novel structures
Two organically templated cadmium borophosphates, (C4H16N3)[CdClB2P3O12(OH)] (1) and (C2H10N2)[CdB2P3O12(OH)] (2), were synthesized hydrothermally in the presence of structure-directing amines. Compound 1 has a complex layered structure (orthorhombic, Pbca (No. 61); a = 9.470(2), b = 12.307(3), c = 27.311(6) Angstrom; V = 3183 (1) Angstrom(3); Z = 8) with a 9MR channel system, while compound 2 (orthorhombic, Pbca (No. 61); a = 9.286(3), b = 12.459(3), c = 21.626(6) Angstrom; V = 2502(1) Angstrom(3); Z = 8) presents a 3-dimensional open framework structure of different types of intersecting channels. It is worth noting that both the Cl- anions and the organic templates play important and interesting roles in the formation of the structures.
