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(Ƙ¹-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.
