Abstract

The structure of 1,3-bis(2,4,6-trimethylphenyl)-imidazol-2-ylidene-silver(I) chloride, 1, has been determined to be a monomer with weak head-to-tail H...Cl interactions in the solid state. A multinuclear NMR study using a (13)C(carbene) labeled derivative, 1((13)C), exhibits (13)C-(107,109)Ag coupling in solution. Further, the solid state CP/MAS NMR parameters, including the principal components of the chemical shift tensors for both the (13)C and (109)Ag centers, have been determined. With the aid of DFT calculations, the orientation of the chemical shift tensors have been assigned.
