Abstract
Pressures of saturated and unsaturated vapors of dimethylformamide (C3H7NO) in the host (organometallic framework [Zn4(dmf)(ur)2(ndc)4]) and guest (C3H7NO) system are measured using static tensiometry with membrane null-manometers across the 305–459 K range of temperatures. Temperature dependences of the pressures for the guest transition from the host framework into the gas phase are obtained from the experimental data. The enthalpies and entropies of these processes are determined, and the change in Gibbs energy during the bonding of C3H7NO to the framework is calculated. The obtained data are used to draw conclusions about the nature of interactions between the organometallic framework and dimethylformamide. Findings are compared to previously studied sorption processes of water, benzene, and ferrocene on [Zn4(dmf)(ur)2(ndc)4].
