1-异丙基-3,5-二吡啶基-6-氧代过达嗪与钴的配位会产生双阳离子，最好在固态下描述为与两个具有 S = 3/2 基态的自由基配体配位的高自旋钴 (II) 离子。在乙腈中溶解后，钴 (II) 形式与 S = 1/2 基态的钴 (III) 价互变异构体达到平衡。
Coordination of 1-isopropyl-3,5-dipyridyl-6-oxoverdazyl to cobalt results in a dication best described in the solid state as a high spin cobalt(II) ion coordinated to two radical ligands with an S = 3/2 ground state. On dissolution in acetonitrile, the cobalt(II) form equilibrates with a cobalt(III) valence tautomer with an S = 1/2 ground state.
