Unsymmetrical Bis(iminoethyl)pyridine Metal Complexes with a Pendant Alkenyl Substituent. Part B: Internal Olefin Coordination to Ruthenium

Antimony diiminopyridine complexes

The stoichiometric reactions of antimony trichloride, trimethylsilyl trifluoromethanesulfonate, and diiminopyridine ligands lead to the formation of N,N',N''-chelated SbCl₂ cationic complexes. Methyl and phenyl substituents on the imine carbons of the ligand yielded structures with a lone pair on antimony and the hydrogen substituted variant was notably different as it forms a Menshutkin complex with meta-xylene in the solid-state.
