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