The new complexes, M(CO)5(Hsalesh) (M = Cr (1), Mo (2), W (3)), Re(CO)4Br(Hsalesh) (4) and Mn(CO)3(Hsalesh) (5) have been synthesized by the photochemical reaction of metal carbonyls M(CO)6 (M = Cr, Mo, W), Re(CO)5Br, and Mn(CO)3Cp with salicylaldehyde ethanesulfonyl hydrazone (Hsalesh). The complexes have been characterized by elemental analysis, EI mass spectrometry, FT-IR and 1H NMR spectroscopy. The spectroscopic studies show that Hsalesh behaves as a monodentate ligand coordinating via imine N donor atom in M(CO)5(Hsalesh) (M = Cr, Mo, W) and Re(CO)4Br(Hsalesh) and as a tridentate ligand in Mn(CO)3(salesh).
