Figure 3

UV-vis spectra of H2Q2 (a) and absorbance measured at λ 316 nm in the presence of increasing amounts of MnII (aqueous solution, pH 7.4, [H2Q2 = 1.1·10−4 M]), and proposed structures of the MnM2 and MnQ2 complexes (in MnQ2 one or both quinoline moieties can be involved in metal coordination: only the case with both the quinoline units interacting with MnII is represented).
