SYNTHESIS AND CHARACTERIZATION OF THE PRODUCTS FROM REACTION OF METAL CARBONYLS (M(CO)6 (M ¼ Cr, Mo, W), Re(CO)5Br, Mn(CO)3Cp) WITH SALICYLALDEHYDE METHANESULFONYLHYDRAZONE

Five new complexes, [M(CO)5(salmsh)] (M = Cr; 1, Mo; 2, W; 3), [Re(CO)4Br(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, EI mass spectrometry, FT-IR and 1H 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.
