In the paper, the multidentate carboxylic acid ligands were used to combine with Cd, resulting in the three dimensional MOCPs single crystals—C12H16CdN2O8, with a low temperature hydrothermal synthesis method. The sample was characterized with IR spectra to affirm the organic groups in the frameworks, single-crystal X-ray diffraction to determine the crystal structure and composition of the frameworks, N2 adsorption isotherms at low temperature to measure the specific surface area and pore size distribution, and with TGA/DGA analysis to scale the thermal stability. Furthermore, the dissolution property and the photocatalytic activity of MOCPs under the ultraviolet ray condition were explored.
