Chirality at Metal in a Linear [Ag(NHC)2]+ Complex: Stereogenic C−Ag−C Axis, Atropisomerism and Role of π‐π Interactions

Year: 2024

Type: article

Abstract: Chirality at the metal center is a well‐established concept, exemplified by numerous four‐ and six‐coordinated complexes. Here, a pioneering example of linear chirality‐at‐metal is described: [Ag(NHC)2]+ (NHC=N‐heterocyclic carbene). In solution, stabilizing π‐π interactions preserve the chiral information of the solid state. Consequently, a novel class of atropisomers is identified, whose stereogenicity arises from hindered rotation around a C−Ag−C axis, instead of a typical C−C bond.
