Manganese corroles with the Mn atom in the oxidation states +III and +IV have been probed as donor moieties for supramolecular stacked donor–acceptor complexes with the typical acceptor units TCNQ (tetracyanoquinone), TCNP (tetracyanopyrazine), and TCNB (tetracyanobenzene). Four new compounds formed as single crystals from different co-crystallization attempts. In those cases where a Mn(III) corrole was used as the donor component, hydrolyzed and/or oxygenated compounds [(cor)Mn(TCNQ*)] and [(cor*)Mn(TCNP*)] were obtained as the exclusive products. With chloridomanganese(IV) corroles, sandwich-like 2:1 complexes [(cor)MnCl]2[TCNQ] and [(cor)MnCl]2[TCNB] form, with both components left intact. Crystallographic analyses reveal partial or complete charge transfer to unusual axial ligands and thus prove the high reactivity of Mn(III) corroles in the first two cases. For the sandwich arrangements, almost-unaltered geometric parameters of the Mn(IV) corroles are observed, pointing to negligible structural consequences for metal corroles when engaged in stacking interactions.

锰与 TCNQ 和相关受体分子的相互作用

具有氧化态 +III 和 +IV 的 Mn 原子的锰原子已被探索为具有典型受体单元 TCNQ（四氰基醌）、TCNP（四氰基吡嗪）和 TCNB（四氰基苯）的超分子堆叠供体-受体复合物的供体部分。四种新化合物通过不同的共结晶尝试形成单晶。在将 Mn(III) corrole 用作供体组分的情况下，水解和/或氧化化合物 [(cor)Mn(TCNQ*)] 和 [(cor*)Mn(TCNP*)] 作为唯一的产品。与氯化锰 (IV) corroles，三明治状 2:1 配合物 [(cor)MnCl]2[TCNQ] 和 [(cor)MnCl]2[TCNB] 表格，两个组件都保持不变。晶体学分析揭示了部分或完全电荷转移到不寻常的轴向配体，从而证明了前两种情况下 Mn(III) corroles 的高反应性。对于夹层排列，观察到几乎未改变的 Mn(IV) corroles 的几何参数，这表明当从事堆叠相互作用时金属 corroles 的结构后果可以忽略不计。
