The copper(II) complex of the tetrameric Schiff base tetrabenzo[b,f,j,n][1,3,9,13]tetra-aza-cyclohexadecine (tetra-anhydroamino benzaldehyde), Cu(TAAB)²⁺, is known to exhibit superoxide dismutase mimetic behaviour. Therefore, investigations dealing with Cu(TAAB)²⁺ are of special interest from the bioinorganic point of view. The structure and electrochemistry, as well as the reaction kinetics in physiological relevant surroundings, are well investigated, but a vibrational characterization - especially regarding the copper coordination site - has not been performed so far. Our aim was therefore to elucidate the bond strengths and vibrational features especially in respect to the copper(II) coordination site. The present study is shedding light on these properties by vibrational investigations performed in the far IR and quantumchemical calculations. The experimental data are interpreted by a complete normal coordinate analysis on semi-empirical level.
