Abstract

Five new complexes, [M(CO)(5)(salmsh)] (M=Cr;1,Mo;2,W;3), [Re(CO)(4)Br(salmsh)], 4, and [Mn(CO)(3) (salmsh)], 5, have been synthesized by the photochemical reaction of metal carbonyls with salicylaldehyde methanesulfonylhydrazone (salmsh). The complexes have been characterized by elemental analyses, El mass spectrometry, FT-IR and H-1 NMR spectroscopy. The spectroscopic studies show that salmsh behaves as a monodentate ligand coordinating via the imine N donor atom in 1-4 and as a tridentate ligand in 5.
