Abstract

Reaction of iron(II) and the 3 : 1 Schiff base condensate of 5-methylpyrazole-3-carboxaldehyde and tris(2-aminoethyl)amine in air gives a pseudo-dimer complex with a triple helix structure made of Delta-Delta and Lambda-Lambda pairings of spin crossover iron(II) and low spin iron(III) cations that are held together by three pi-pi and hydrogen bonding interactions.

摘要

在空气中，亚铁离子与5-甲基吡唑-3-甲醛和三（2-氨基乙基）胺的3:1席夫碱缩合物反应，生成一种具有三重螺旋结构的假二聚体配合物，该结构由自旋交叉亚铁离子和低自旋铁（III）阳离子的δ-δ和λ-λ配对组成，它们通过三种π-π和氢键相互作用结合在一起。
