Study of interaction of rhenium (5) and molybdenum (5) oxopentahalides with 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane

Processes of complexing of rhenium (5) and molybdenum (5) with macrocyclic ligand 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (Tet a) were studied. It is ascertained that in the medium of hydrogen halide acids onium complexes are formed (H2Tet a) [EOX5], where E=Re, Mo; X=Cl, Br. Interaction of [EOX5]2-with Tet a in nitromethane results in formation of molecular and cation-type complexes: [EO(Tet a)Cl3] and [EO(Tet a)Br]Br2. The composition and structure of the compounds prepared are ascertained in the basis of element analysis, conductometry, IR-spectroscopy in the far and near ranges
