·pyNO (X = F, Cl, Br or I; pyNO = pyridine N-oxide) and Cu(2BrC 6 H 4 COO) 2 ·picNO (picNO = 2-, 3-, or 4-picoline N-oxide) is described. The spectroscopic and magnetic behaviours of the compounds are compared with those of binuclear copper(II) alkanoates. The EPR spectra of the powdered solid are consistent with spin S = 1. The exchange interaction parameters are −2J ≈ 380 cm −1 , except for Cu(21C
