Utilizing facile one-electron oxidation of 10H-phenothiazine by molecular diiodine, the solid-state structure of the 10H-phenothiazinium radical cation was obtained in three cation:iodide ratios, as well as its THF and acetone solvates. Oxidation of 10H-phenothiazine with molecular diiodine in DMSO or DMF provided the structure of the radical coupling product 10-(3-phenothiazinyldene)phenothiazinium, which has not been crystallographically characterized to date. The radical cations were balanced by a mixture (I ) , (I ) , (I ) , and I anions, where a variety of chalcogen, halogen, and hydrogen bonding interactions stabilize the structures to reveal these interesting cationic species.
利用分子碘对10H-吩噻嗪进行简便的单电子氧化，在三种阳离子与碘化物比例下获得了10H-吩噻嗪鎓自由基阳离子的固态结构，以及其四氢呋喃和丙酮溶剂化物。在二甲基亚砜或二甲基甲酰胺中用分子碘氧化10H-吩噻嗪得到了自由基偶联产物10-(3-吩噻嗪基亚甲基)吩噻嗪鎓的结构，该结构迄今尚未通过晶体学表征。自由基阳离子由(I⁻)、(I₂⁻)、(I₃⁻)和I⁻阴离子的混合物平衡，其中各种硫族元素、卤素和氢键相互作用使结构稳定，从而揭示了这些有趣的阳离子物种。
