Copper(II) complexes of new N ‐benzothiazole sulfonamides (HL1= N ‐2‐(benzothiazole)naphtalensulfonamide and HL2 = N ‐2‐(6‐chlorobenzothiazole)toluenesulfonamide) with ethylenediamine (en) and diethylenetriamine (dien) have been synthesized and characterised. The crystal structures of [Cu(dien) 2 ](L1) 2 ( 1 ) and [Cu(en) 2 (H 2 O) 2 ](L2) 2 ( 2 ) compounds have been determined. The metal centre adopts a “4+2” distorted octahedral environment in both complexes. Unusually, the sulfonamidate anions act as counterions. Spectroscopic properties are in good agreement with the crystal structures. The superoxide dismutase (SOD)‐like activity of complex 2 has been tested.
