The inclusion compounds, based on the metal-organic frameworks (MOFs), have promising practical application in gas storage, separation and fine purification of substances, and also in catalysis. These MOFs are crystalline compounds consisting of metal ions coordinated by bridging organic ligands with the formation of porous structures. We study the kinetic stability of the inclusion compound: [Li2(H2btc)]·dioxane (H4btc = 1,2,4,5-benzenetetracarboxylic acid, 1,4-dioxane = C4H8O2). The connection between the kinetic stability of inclusion compounds and the properties of the host matrix and of the guest molecules is considered. So as the centrosymmetric dioxane molecule can easily transform the chair conformation to the bath conformation, it can have the influence on the steric hindrance (as well as on the activation barrier) for the guest molecules removal. Therefore, the entropy contribution is as favorable factor, as the energetic one in the kinetic stability of the supramolecular compounds.
