Malek and Arumugam: μ-Chlorido-bis{[1-benzyl-3-(2,4,6-trimethylphenyl)imidazol-2-ylidene-κC]silver(I)} chloride 1,2-dichloroethane hemisolvate #CrystalStructure #NHeterocyclicCarbene #SilverChloride #IUCr https://journals.iucr.org/paper?S2414314624008617
The solid-state structural analysis of the title compound reveals that the two molecules of bis(1-benzyl-3-mesitylimidazol-2-ylidene)silver are connected via a bridging chloride atom. The structure also reveals non-classical intermolecular hydrogen-bonding interactions involving the chloride counter-anion.

A diiron end-on μ2-η1:η1-CN-bridged complex is obtained from a crystallization experiment of an open-chain iron–NHC complex. The cyanide appears to originate from the acetonitrile (MeCN) solvent by C—C bond cleavage or through carbon–hydrogen oxidation.
