Palladium, cadmium and mercury complexes of 2-((2-((2-hydroxyethyl)amino)ethyl)amino)cyclohexanol: Synthesis, structural, spectral and solution studies

The reaction between 2-(2-amino-ethylamino)ethanol and cyclohexene oxide gives 2-((2-((2-hydroxyethyl)amino)ethyl)amino)cyclohexanol, HEAC. Four complexes of HEAC, including [Pd(HEAC)Cl2], [Cd2(HEAC)2(μ-Br)2Br2], [Cd(HEAC)(OAc)2] and [Hg(HEAC)Cl2], were prepared and identified by elemental analysis, FT-IR, Raman, 1H NMR spectroscopy and single-crystal X-ray diffraction. The redox properties of HEAC and the complexes were investigated by cyclic voltammetry experiments.
