The catalytic properties of Cu 2+ ‐chelates of the following ligands in H 2 O 2 decomposition have been investigated: N, N′‐diglycyldiaminoethane (I), N, N′‐diglycyl‐1,5‐diaminopentane (II), N, N′‐diglycyl‐1,3‐diaminopropane (III) [6], glycinamide (IV), glycylglycinamide (V) and polymyxin B (VI). It is confirmed that the catalysis of H 2 O 2 decomposition by Cu 2+ ‐chelates and the formation of ternary peroxo complexes (absorbing at 360 nm) depend on the number of free coordination positions. It is now shown that in reversal the number of free coordination positions on the Cu 2+ in its complexes can be determined by measuring their catalytic activity on the H 2 O 2 decomposition, and their absorption at 360 nm.
