reactions of metal hexacarbonyls M(CO)6 (M = Cr, Mo, W) with the radical anions of 2,1,3-benzoxadiazole, 2,1,3-benzothiadiazole and 2,1,3-benzoselenadiazole yield paramagnetic mono- and bi-nuclear metal pentacarbonyl The ligand-centered radicals were identified and studied in THF solution by electronspinresonance, Hückel MO calculations were employed to account for the spin redistribution in the radical
