monomeric Mn I I complex with the tridentate N-centered N 3 ligand tris[(1-methyl-2-imidazolyl)methyl]amine (TMIMA) ([Mn I I (TMIMA) 2 ] 2 + ); and(b) the structure of a monomeric Mn I I I complex with the tridentate N-centered N 2 O ligand 2-[(1-methyl-2-imidazolyl)methyl]amino}phenolate (PI - ) [ 2 ] ([Mn I I I (PI) 2 ] + ) (5). The latter was isolated both in the Mn I I and in the Mn I I I state
本文描述了两种晶体结构:(a) 单体 Mn II 配合物与三齿 N 中心 N 3 配体三[(1-甲基-2-咪唑基)甲基]胺 (TMIMA) ([Mn II (TMIMA) 2 ] 2 + ); (b) 单体 Mn III 配合物与三齿 N 中心 N 2 O 配体 2-[(1-methyl-2-imidazolyl)methyl]amino}phenolate (PI - ) [ 2 ] ([Mn III (PI) 2 ] + ) (5)。后者在 Mn II 和 Mn III 状态下都被分离出来,尽管只有 Mn III 晶体成功生长。它们是作为 SOD 模拟物制备的一系列 Mn 配合物的一部分,即 [Mn(BMPG)(H 2 O)] + (2) BMPG = N,N-bis[(6-methyl-.2-pyridyl)methyl ]甘氨酸}, [Mn(IPG)(MeOH)] + (3) IPG
