The diiodine basicity (a soft Lewis basicity) of 15 azoles (imidazoles, pyrazoles and triazoles) was measured by means of the formation constant of the diiodine-azole complexes in heptane at 298 K. The preferred sites of diiodine fixation are the nitrogens N-3 in imidazoles, N-2 in pyrazoles and N-4
