Solid Cu(2-Benzoylpyridine)2(NO3)2has been studied by UV-Vis, IR, and EPR (X-band, Q-band) techniques. Monoclinic crystal symmetry was determined with two molecules per unit cell. Copper (II) is coordinated by two benzoylpyridine ligands and a single NO3group in the chromophore CuN2O3of distorted trigonal bypiramidal stereochemistry. Exchange coupling values were determined from EPR spectra as |J| = 0.0026(2) cm−1between magnetically nonequivalent copper (II) sites, and |J| < O.3 cm−1between equivalent sites.
