Tren 配体具有很好的热力学和动力学稳定性[1],因为它是四齿配体可以和铀形成稳定U-N 键,并以四价铀为中心金属原子,形成口袋型的U-Cl化合物(图1)。基于该铀配合物的化学反应获得了很大发展,但也仅限于少数已经报道的U-C、U-N、U-O、U-S、U-Se、U-Te 和U-P 多重化学键的形成。
Lanthanide clusters have been widely applied to molecular magnetic materials,such as single molecule magnets and magnetic coolers,owing to their distinctive and novel structures[1,2].
Three hexacoordinated octahedral nickel(Ⅱ)complexes,[Ni(sal-L-phe)(phen)(CH3OH)](1),[Ni(naph-L-phe)(phen)]CH3OH(2)and [Ni(o-van-L-phe)(phen)(CH3OH)]·5H2O(3)(sal-L-phe = a Schiff base derived from sali
Single-chain magnets(SCMs)have received wide attention because of their potential applications in high-density information storage and quantum computation.
