Synthesis and characterization of metal carbonyls [M(CO)(6)(M = Cr, Mo, W), Re(CO)(5)Br, Mn(CO)(3)C-P] with 2-hydroxy-1-napthaldehyde ethanesulfonylhydrazone (nafesh)

WOS: 000188262900015Five new complexes, M(CO)(5)(nafesh) (M = Cr (1), Mo (2), W (3)), Re(CO)(4)Br(nafesh) (4) and Mn(CO)(3)(nafesh) (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 2-hydroxy-1-napthaldehyde ethane-sulfonylhydrazone (nafesh). The complexes have been characterized by elemental analysis, El mass spectrometry, FT-IR, H-1 NMR spectroscopy. The spectroscopic studies show that nafesh behaves as a monodentate ligand coordinating via imine N donor atom in M(CO)(5)(nafesh) (M = Cr, Mo, W) and Re(CO)(4)Br(nafesh) and as tridentate ligand in Mn(CO)(3)(nafesh)
