In the title complex, Mn(C20H21N3)22, two tridentate (2-methyl-benz-yl)bis-(pyridin-2-ylmeth-yl)amine (L) ligands form the Mn(II) complex MnL 22. The Mn(II) ion lies on a twofold axis and the complex cation is significantly distorted from regular octa-hedral geometry. The packing is stabilized by weak C-H⋯O inter-actions between the cations and anions, which link them into a zigzag ribbon along [101]. The perchlorate anion is disordered and was constrained to be tetra-hedral with two orientations having occupancies of 0.768 (4) and 0.232 (4). The 2-methylbenzyl moiety is also disordered over two sets of sites, with occupancies of 0.508 (15) and 0.492 (15).
在标题配合物Mn(C₂₀H₂₁N₃)₂₂中,两个三齿的(2-甲基苄基)双(吡啶-2-基甲基)胺(L)配体形成了Mn(II)配合物MnL₂₂。Mn(II)离子位于二重轴上,配合物阳离子明显偏离正八面体几何构型。阳离子和阴离子之间的弱C-H⋯O相互作用使堆积得以稳定,这些相互作用将它们沿[101]连接成一条锯齿状带。高氯酸根阴离子无序,被限制为四面体,有两种取向,占有率分别为0.768 (4)和0.232 (4)。2-甲基苄基部分也在两组位置上无序,占有率分别为0.508 (15)和0.492 (15)。
