A new three-dimensional (3D) framework cadmium germanium phosphate, CdGe(OH){sub 3}PO{sub 4} was synthesized by solvothermal methods. The crystal structure of CdGe(OH){sub 3}PO{sub 4} was established by single-crystal X-ray diffraction: CdGeH{sub 3}O{sub 7}P, Orthorhombic, Cmca, a=7.1415(7) A, b=10.9034(1) A, c=13.1098(1) A, Z=8, R{sub 1}=0.0365 (F{sup 2}>2{sigma}(F{sup 2}) and wR{sub 2}=0.0985 (all data). The framework of CdGe(OH){sub 3}PO{sub 4} is built by a mixed network of GeO{sub 6}, CdO{sub 6} octahedra and PO{sub 4} tetrahedra, which are linked to form a 3-membered ring (3-MR). The GeO{sub 6} and CdO{sub 6} octahedra share common vertexes and edges, respectively, to form one-dimensional (1D) Ge-O-Ge and Cd-O-Cd chains, which are further connected forming corrugated Ge-O-Cd layers. The layers are linked by PO{sub 4} tetrahedra, leading to a 3D open-framework structure with 3- and 6-MR channels. - Graphical abstract: A new three-dimensional framework cadmium germanium phosphate, CdGe(OH){sub 3}PO{sub 4} was synthesized by solvothermal methods.

It belongs to a class of metal germanium phosphates with an open framework.
