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) Å; V = 3183
(1) Å3; 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) Å; V = 2502(1) Å3; 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.
