Alkali and alkaline earth perchlorate and picrate complexes with some macrocyclic polyethers
Crystalline complexes of some alkali and alkaline earth Perchlorates and picrates with macrocyclic polyethers have been synthesized. With the alkyl substituted aromatic macro-cyclic polyethers bis(3,5-di-£er£-butylbenzo)-18-crown-6 and bis(4-hexadecylbenzo)-18-crown-6 it was not possible to isolate all the complexes in the crystalline form. In fact the steric hindrance, caused by the alkyl substituents, affects the stability of the complexes and hinders the possibility of isolation. It has been observed that also the molecular structure and the electronic configuration of the anion are important factors in determing the formation of crystalline complexes. The complexes obtained were identified and characterized by elemental analysis, IR, UV and iH NMR spectra, conductivity and x-ray powder analysis.
