They often form adducts with a variety of donor atoms in an unselective manner. We have characterized the adducts formed between a series of isostructural N -heterocyclic carbene (NHC) complexes with Ru, Os, Rh, and Ir centers and the model protein hen egg white lysozyme by X-ray crystallography and mass spectrometry. Distinctive behavior for the metal compounds was observed with the more labile Ru and Rh complexes targeting a surface l-histidine moiety through cleavage of p- cymene or NHC co-ligands, respectively. In contrast, the more inert Os and Ir derivatives were detected in an electronegative binding pocket after undergoing ligand exchange of a chlorido ligand for an amino acid side chain. Computational studies supported the binding profiles and hinted at the role of the protein microenvironment for metal complexes eliciting selectivity for specific binding sites on the protein.
