Abstract

Inclusion compounds based on metal-organic frameworks (MOFs) have promising practical application in gas storage, separation and fine purification of substances, as well as in catalysis. MOFs are crystalline compounds consisting of metal ions coordinated by bridging organic ligands that form porous structures. The kinetics of the thermal decomposition of the frameworks themselves, namely [Co2(camph)2bpy] and [Co2(asp)2bpy], was investigated (camph and asp are the anions of camphoric and aspartic acids, bpy is the organic amine, 4,40-bipyridyl). The empty coordination polymer framework based on metal camphorates was thermally (kinetically) less stable than the polymer framework based on metal aspartate. A high kinetic stability of frameworks with aspartic complexes during heating was due to the entropic factor rather than the enthalpic one.
