Abstract

Herein two unprecedented octanuclear Co8 clusters are presented, [Cl@Co8 (TEOA)4(CH3CN)Cl3] (1) and [S@Co8(DEOA)6(NCS)2] (2) (H3TEOA = triethanolamine, H2DEOA = diethanolamine), in which tetrahedral μ4-chloride and in situ generated octahedral μ6-sulfide are used as templates. In spite of them being derivatives of cubes, eight Co atoms in 1 consist of two co-centered tetrahedra of different sizes, whereas in 2 they appear as a rhombohedron formed via elongating a cube along the C3-axis direction. Strong intra-cluster antiferromagnetic interactions were found.

摘要

本文报道了两个前所未有的八核钴簇合物，[Cl@Co8(TEOA)4(CH3CN)Cl3] (1) 和 [S@Co8(DEOA)6(NCS)2] (2)（H3TEOA = 三乙醇胺，H2DEOA = 二乙醇胺），其中四面体μ4-氯和原位生成的八面体μ6-硫化物用作模板。尽管它们是立方体的衍生物，但1中的八个钴原子由两个不同大小的共心四面体组成，而在2中它们呈现为通过沿C3轴方向拉长立方体形成的菱面体。发现了强烈的簇内反铁磁相互作用。
