Formation of novel ene-yne substituted β-diketonato ruthenium(III) complexes by the Heck-like reactions on coordinated ligand

► Identification of two novel ene-yne substituted β-diketone Ru complexes. ► Formation of the complexes by the Heck-like reactions. ► Ethene plane on coordinated β-diketonate is fixed with canting to chelate plane.
