A new oxamido‐bridged macrocyclic trinuclear complex {[(CuL)(EtOH)] 2 Cd(EtOH) 2 }(ClO 4 ) 2 · H 2 O (H 2 L = 2,3‐dioxo‐5,6:13,14‐dichlorobenzo‐7,12‐diphenyl‐1,4,8,11‐tetraazacyclo‐pentadeca‐7,11‐diene)was synthesized and structurally characterized. The central Cd II ion of the complex is bridged by macrocyclic oxamido groups. Magnetic properties were studied by susceptibility vs. temperature measurement, the best fitting of the experimental data led to J = –0.59 cm –1 . IR and EPR spectra were also investigated.
