Mesitylene Tribenzoic Acid as a Linker for Novel Zn/Cd Metal-Organic Frameworks.

Three new Metal-Organic Frameworks, containing mesitylene tribenzoic acid as a linker and zinc () or cadmium as metals (,), were synthesized through solvothermal reactions, using DMF/ethanol/water as solvents, at temperatures of 80 °C (structures and ) and 120 °C (structure ). Following single-crystal X-ray diffraction, it was found that and crystallize in the 2/ and C2/ space groups and form 2D networks, while crystallizes in the 2 space group, forming a 3D network. All three frameworks, upon heating, were found to be stable up to 350 °C. N sorption isotherms revealed that displays a BET area of 906 m/g. Moreover, the porosity of this framework is still present after five cycles of sorption/desorption, with a reduction of 14% of the BET area, down to 784 m/g, after the fifth cycle. The CO loading capacity of was found to be 2.9 mmol/g at 0 °C.
