3D Cobalt(II)-based MOF: Synthesis, structure, thermal decomposition behavior and magnetic property

Abstract

A porous metal-organic framework (PMOF) [Co2(dtb)2Cl2]·Cl2·3H2O (1) with 4,4′-di(4H-1,2,4-triazol-4-yl)-1,1′-biphenyl (dtb) as organic ligand, was hydrothermally assembled and structurally characterized by single crystal X-ray diffraction analysis. In compound 1, Co2+ ions exhibit a six-coordinated geometry to link triazole of dtb ligand and Cl− ions, resulting in a fascinating architecture. The thermostability was estimated and non-isothermal kinetics was also examined at different heating rates by Kissinger's and Ozawa-Doyle's method. In addition, the magnetic behavior was described and discussed in the temperature range of 2–300 ​K under an applied dc field of 1000 ​Oe.
