Copper (II) and H+ complexes of 3, 3, 8, 8-tetramethyl-4, 7-diazadecane-2, 9-dione dioxime, 3, 3, 9, 9-tetramethyl-4, 8-diazaundecane-2, 10-dione dioxime and 3, 3, 10, 10-tetramethyl-4, 9-diazadodecane-2, 11-dione dioxime have been studied at 25° C and ionic strength 0.15 mol dm–3 NaCl, using glass-electrode potentiometry. Electronic spectra have been used to postulate structures for the different species in solution. In each case the metal binds to the ...
