The new complexes, M(CO)(5)(Hsalesh) (M = Cr (1), Mo (2), W (3)), Re(CO)(4)Br(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)(5)Br, and Mn(CO)(3)Cp with salicylaldehyde ethanesulfonyl hydrazone (Hsalesh). The complexes have been characterized by elemental analysis, EI mass spectrometry, FT-IR and H-1 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)(4)Br(Hsalesh) and as a tridentate ligand in Mn(CO)(3)(salesh).
