The thermal decomposition of three inclusion compounds: [Zn2(camph)2dabco]·DMF·H2O, [Zn2(camph)2bipy]·3DMF·H2O and [Zn2(camph)2bpe]·5DMF·H2O was studied in the inert atmosphere. TG and DTG curves confirm multi-step decomposition process, the dehydration being the first step. Thermogravimetric data (obtained at different rates of linear heating) were processed with computer program (with ‘Model-free’ approach). Kinetic parameters of decomposition were calculated for the DMF multi-step removal, the processes are described by Avrami–Erofeev equations. The connection between the kinetic parameters and structural features of the host frameworks (ligand linker lengths and porous-free volumes) are discussed.
