New half-sandwich ruthenium (II) complexes [η⁶‒p-cymene)Ru (L_1-3)Cl] (1–3) containing biphenylamine based Schiff base ligands (HL_1-3) have been synthesized and characterized by analytical and spectroscopic methods. Additionally, the solid state structure of 2 has been determined by single crystal X-ray diffraction study. The complex 2 serves as a catalyst for the amidation of various aldehydes to amides in good yield.
