The structural, magnetic and theoretical aspects are described for three triangular lanthanide complexes, [Tb(OH)(teaH)(paa)]Cl (1), [Dy(OH)(teaH)(paa)]Cl (2) and [Ho(OH)(teaH)(paa)]Cl (3), and a hexanuclear wheel of formula [Dy(pdeaH)(NO)] (4) [teaH = triethanolamine, paaH = N-(2-pyridyl)-acetoacetamide and pdeaH = 3-[bis(2-hydroxyethyl)amino]propan-1-ol]. Each complex displays single molecule toroidal behaviour as rationalised using high-level ab initio calculations. Complexes 2 and 3 are the first examples of mixed moment single molecule toroidal complexes featuring non-Kramers ions.
描述了三个三角镧系元素配合物的结构、磁性和理论方面，[Tb(OH)(teaH)(paa)]Cl（1）、[Dy(OH)(teaH)(paa)]Cl（2）和[Ho(OH)(teaH)(paa)]Cl（3），以及一个六核轮式配合物[Dy(pdeaH)(NO)]（4）[teaH = 三乙醇胺，paaH = N-(2-吡啶基）-乙酰丙酮酸，pdeaH = 3-[双(2-羟乙基)氨基]丙-1-醇]。每个配合物都表现出单分子环形行为，这可以通过高级从头算计算来合理化。配合物 2 和 3 是第一个具有非克拉默离子的混合磁矩单分子环形配合物的例子。
