We report nine new homoleptic octahedral cobalt(II) complexes [Co((NN)-N-boolean AND)(3)](2+) and [Co((NNN)-N-boolean AND-N-boolean AND)(2)](2+) with bidentate or tridentate azole-pyridine ligands (where azole is 1,2,4-triazole or a substituted pyrazole). The complexes are air-and moisture-stable solids of pale pink to pale brown color that exhibit quasireversible redox processes in polar organic solvents. By changing azole heterocycle and by adding methyl groups, we tune redox potentials of the complexes from 0.05 to 0.5 V for the Co(III/II) couple (its cyclic voltammogram depends on the electrode history) and from -1.08 to -1.57 V for the Co(II/I) couple to give a redox gap of 1.37-1.82 V. Replacing a pyrazole with electron-deficient 1,2,...
