Abstract

The structurally related odd and even numbered wheels [Fe Zn (tea) (teaH) (OMe)Cl ] (1) and [Fe Zn (tea) Cl ] (2) can be synthesized under ambient conditions by reacting Fe and Zn salts with triethanolamine (teaH ), the change in nuclearity being dictated by the solvents employed. An antiferromagnetic exchange between nearest neighbors, J = -10.0 cm for 1 and J = -12.0 cm for 2, leads to a frustrated S = 1/2 ground state in the former and an S = 0 ground state in the latter.

摘要

结构相关的奇数和偶数编号轮状化合物[Fe₂Zn₂(tea)₂(teaH)₂(OMe)Cl₂] (1)和[Fe₂Zn₂(tea)₂Cl₂] (2)可在环境条件下通过使铁盐和锌盐与三乙醇胺(teaH₂)反应合成，核数的变化由所使用的溶剂决定。相邻原子间的反铁磁交换，对于1，J = -10.0 cm⁻¹，对于2，J = -12.0 cm⁻¹，导致前者出现受挫的S = 1/2基态，后者出现S = 0基态。
