The stearic acid-urea binary system exhibits an unusual phase diagram, which, on the one hand, indicates an incongruently
melting inclusion compound and on the other hand a miscibility gap in the liquid phases. The peritectic point lies near the
melting point of urea and the unstable congruent melting point of the inclusion compound coincides with the melting point
of urea. In addition to the processing of the phase diagram, the pure inclusion compound was prepared and its DSC curve, FTIR
spectrum and X-ray diffractogram were recorded.
The thermal decomposition of two inclusion compounds Mn(HCOO)2·1/3C4H8O2 and Mn(HCOO)2·1/3C4H8O was studied in the inert atmosphere. The process of both dioxane, and tetrahydrofurane removal has two steps; the intermediate
phase is unstable and kinetically hindered. Manganese formate is stable up to 330°C. Thermogravimetric data (obtained at different
rates of linear heating) were processed with computer program (with ‘Model free’ approach). Kinetic parameters were calculated
for the first decomposition step, and the process is described by equation of n-order reaction with autocatalysis.
-temperature fluorination (C x F) n [ 3 ]. The properties of FGIC were studied mostly for the compounds that are stable in the air.
Fluorinated graphite intercalation compounds are layered inclusioncompounds based on the polymeric two-dimensional fluorographite
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.
Thermodynamic and kinetic stability of inclusion compounds (so called supermolecular compounds) is discussed. Compounds under
study and discussion are clathrates (with coordination compounds matrices) and intercalates (with fluorinated graphite matrices).
This article explored the stability of the important part of supramolecular compounds: inclusioncompounds, based on coordination compounds as host matrices.
Many different inclusioncompounds are currently
Three isomorphous series of new compounds are reported: complexes [M(DBM)2Q2] and [M(DBM)2Iq2] (M = M(II) = Co, Ni, Zn, Cd; DBM is C6H5COCHCOC6H5−) and inclusion compounds [M(DBM)2Q2]*Q (M = Co, Zn, Cd). All the compounds comprise a trans configured octahedral complex molecule. Inclusion compounds of modified Zn and Cd DBM complexes are reported for the first
time and their inclusion ability is attributed to the trans isomeric state induced by the bulky Q or Iq ligand. The TG measurements indicate the following order of thermal stability
of the complexes defined by the strength of the metal–ligand bonds: Ni > Co > Cd > Zn. The inclusion compounds do not follow
