Structure and Properties of Tetra-coordinated Zn(Ⅱ)-MOFs Constructed with Trimeric Acid
A new novel Zn(Ⅱ)-MOFs material,namely[ZnBTC·DMF·CH3NH2CH3]n,was synthesized by solvothermal method using the ligands of H3BTC(H3BTC=benzene-1,3,5-tricar-boxylic acid)and the Zn(Ⅱ)salts.Single crystal X-ray diffraction analysis revealed that the complex crystallizes in the monoclinic crystal system of the P21/c space group.The carboxyl group of benzene 1,3,5-tri-carboxylic acid adopts monodentate and bridge-dentate mode to coordinate with Zn(Ⅱ)cations,forming a netlike 3D MOFs structure.The free DMF molecules and dimeth-ylamine cations were filled in the voids of MOFs.Photocatalytic degradation data revealed that the complex acts as a catalyst to inhibit the degradation of meth-ylene blue,methyl orange and rhodamine B under a 250W ultraviolet lamp.
