Vapour pressure of guest and thermodynamic stability of inclusion compounds [Ni(DBM)2Py2]*2G (DBM = dibenzoylmethanate anion, G = pyridine, tetrahydrofurane and chloroform)

Original Article


Temperature dependences of the equilibrium vapour pressure of the guest molecules (G) over inclusion compounds [Ni(DBM)2Py2]*2G (DBM = C6H5COCHCOC6H5 —dibenzoylmethanate anion; Py = pyridine; G = pyridine, tetrahydrofurane and chloroform) were investigated by means of the static membrane procedure. It was established using TGA and DTA methods that both of two guest molecules get detached at the first step of decomposition 1/2[Ni(DBM)2Py2]*2Gs = 1/2[Ni(DBM)2Py2]s + Ggas. The changes of thermodynamic parameters \( (\Updelta {\text{H}}^{0}_{\text{av}} , \Updelta {\text{G}}^{0}_{ 2 9 8} \;{\text{and}}\;\Updelta {\text{S}}^{0}_{\text{av}} ) \) in this process were determined on the basis of the experimental data.
