摘要

Abstract

A new crystal modification of the N-heterocyclic carbene 1,3-bis(2,6-di-isopropylphenyl)-4,5-dichloroimidazol-2-ylidene (IPrCl, 1) is obtained and structurally characterized. The hydrolysis of this compound leads to the formation of the (IPrClH)+Cl– (2) hydrochloride. The [Co3(Piv)4Cl2(IPrCl)2]·2C7H8 (3·2C7H8) mixed-ligand complex is synthesized by the interaction of the [Co(Piv)2]n cobalt pivalate with IPrCl and is characterized by XRD.
