Abstract
The Krafft temperature (ТKr) of 1-alkyl-4-aza-1-azoniabicyclo[2.2.2]octane bromides (Alk = n-CnH2n + 1, n = 14, 16, 18) (D-n) and complexes of them with transition metals [Cu(II), Ni(II), Co(II), La(III)] in water is determined via conductometry and compared their corresponding acyclic analogs (alkyltrimethylammonium bromides). The dependence of the complexes’ ТKr on the structure of the inorganic salts and the hydrophobicity of ligands is established. It is shown that the complexation of D-n with metal nitrates and the shortening of the ligand hydrocarbon radical reduce ТKr.
