Two-stage thermal decomposition of 18-crown-6 and dicyclohexano-18-crown-6 complexes with alkaline earth metal halides as evidence for non-equivalence of macrocycle symmetry
Thermal stability of macrocyclic complexes with alkaline earth metal salts is of crucial importance for their applicability as the components of new electrolytes, ionic liquids and precursors in chemical vapor deposition processes. The complexes of 18-crown-6 and stereoisomeric dicyclohexano-18-crow...

| description | Thermal stability of macrocyclic complexes with alkaline earth metal salts is of crucial importance for their applicability as the components of new electrolytes, ionic liquids and precursors in chemical vapor deposition processes. The complexes of 18-crown-6 and stereoisomeric dicyclohexano-18-crown-6 with alkaline earth metal halides were synthesized and studied by the combination of simultaneous DSC/TGA and FTIR-spectroscopy. The stability of these compounds depended on the size of the cation and anion as follows: Ba
