Mechanismus der Bildung und des Zerfalls von Amidkomplexen, II . Ni 2+ und N, N′‐Diglycyl‐äthylendiamin bzw. N, N′‐Diglycyl‐1,3‐diaminopropan

The kinetics of a two proton transfer between a blue octahedral and a yellow square planar nickel(II) complex with N, N′‐diglycylethylenediamine (I, n = 1) resp. N, N′‐diglycyl‐1, 3‐diaminopropane (I, n = 2) have been studied by spectrophotometry and pH‐stat technique. The structure of these complexes and the mechanism of their interconversion are discussed and their reactions are compared with the analogous reactions of the copper(II)‐N, N′‐diglycyl‐1, 3‐diamino‐propane complexes [1].
