Non-covalent sulfoxide⋯(nitrosyl group) interactions involving coordinated nitrosyl in a Ru(ii) nitrosyl complex with an α-diimine ligand: structural and computational studies

Abstract

Investigation of the X-ray structure of the newly prepared [Ru(NO)(^2,6isopPh₂Aceq)Cl₃] (^2,6isopPh₂Aceq = bis(2,6-diisopropylphenylimino)acenaphthenequinone) complex revealed for the first time the π-hole interaction involving the coordinated nitrosyl group with DMSO as the solvent of crystallization in the crystal lattice. Processing of CSD data showed only one reported structure. A significant feature of the structure is the presence of n → π*, π → σ*, and n → σ* interactions due to the coordinated nitrosyl and chloro groups and DMSO.
