Abstract

Imidazolium salts with complex anions [Co₂Li₂(Piv)₈]^2– are formed as undesirable products of the reactions of heterometallic compound [Co₂Li₂(Piv)₆(Py)₂] with N-heterocyclic carbenes ItBu and IPr. The study of the magnetic properties of complex (HItBu)₂[Co₂Li₂(µ²-Piv)₆(κ¹-Piv)₂] shows that this compound is a single molecule magnet. Slow magnetic relaxation in the complex occurs due to a combination of the direct and Raman mechanisms.

带有杂金属复合阴离子 [Co2Li2(Piv)8]2- 的咪唑盐：合成、结构和磁性能

摘要具有复合阴离子[Co2Li2(Piv)8]2-的咪唑盐是杂金属化合物[Co2Li2(Piv)6(Py)2]与 N-杂环碳化物 ItBu 和 IPr 反应的不良产物。对复合物 (HItBu)2[Co2Li2(µ2-Piv)6(κ1-Piv)2] 的磁性研究表明，这种化合物是一种单分子磁体。复合物中缓慢的磁弛豫是由直接机制和拉曼机制共同作用产生的。
