The thermodynamic stability of inclusion compounds of Zinc(II) and Nickel(II) coordination polymers with chlorobenzene as a guest: The determination of guest vapor pressure by the tensimetric method

The static membrane method was used to study the temperature dependences of equilibrium guest vapor pressure over inclusion compounds of two coordination polymers with chlorobenzene, [M(bipy)(DBM)(2)] center dot 2C(6)H(5)Cl, where M = M(II) = Zn and Ni, bipy = 4,4'-dipyridyl, and DBM = C6H5COCHCOC6H5- is the dibenzoylmethanate anion. The data obtained were used to calculate the thermodynamic parameters of dissociation of these compounds. The regions of their existence and the stoichiometry and character of phase transitions were determined by thermogravimetric and differential thermal analyses.
