Synthesis and Characterization of the products from reaction of Metal Carbonyls [M(CO)₆ (M Cr, Mo, W), Re(CO)₅Br, Mn(CO)₃Cp] with Salicylaldehyde Methanesulfonylhydrazone

Abstract

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.
