The formation of the mixed chelates [Cu AB]n in aqueous solutions containing [Cu A₂]²⁺ (A= bip or phen) and [Cu B] (B=1, 3-propanediamine (tn), β-alaninate ion (β-ala), malonate ion (mal), or pyrocatechol-3, 5-disulfonate ion (tiron)) was studied spectrophotometrically. When B was tn, the mixed chelates were found to be unstable, while in all other cases the formation of the mixed chelates were nearly quantitative, and their Vmax values, shown in Table 1, clearly indicated the same trend as those of the other [Cu AB]n chelates described previously. Solid chelates shown in Table 2 were also obtained and characterized.
