| Abstract: Open-framework metal phosphates have been the subject of intense research owing to their interesting structural chemistry and potential applications in catalysis and ion exchange. The gallium phosphate family has exhibits rich structural chemistry. A novel gallium phosphate Ga3P2O8(OH)3(H2O)(GaPO-CJ36) has been prepared in a hydrothermal reaction system of GaO(OH)-H3PO4-Co(chxn)3Cl3-H2O at 180 ℃ for 7 days. Single-crystal X-ray analysis shows that GaPO-CJ36 crystallizes in the P21/c space group with a=1.833 35(12) nm, b=0.503 94(3) nm, c=1.062 90(9) nm, V=0.982 01(12) nm3, and Z=4. The connection of GaO2(OH)3(H2O) octahedra, PO4 and GaO4 tetrahedra through vertex oxygen atoms forms a three-dimensional open framework, which contains 8-ring channels along the [010] direction. Its structure is composed of interesting [344484] cages, which have not been found in known gallium phosphates. CSD: 416779. | |
