The author studied complexation reactions of rhenium(V) and molybdenum(V) with a macrocyclic ligand 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (Tet a). The authors found that in hydrohalic acid medium, the onium complexes [H{sub 2}(Tet a)][EOX{sub 5}] are formed, with E = Re, Mo; X = Cl, Br. Reactions of [EOX{sub 5}]{sup 2{minus}} with (Tet a) in nitrometane yield complexes of molecular and cation types [EO(Tet a)Cl{sub 3}] and [EO(Tet a)Br]Br{sub 2}. Composition and structure of the obtained compounds are established by elemental analysis, conductometry, and mid- and far-IR spectroscopy.
