Abstract

Five new complexes, [M(CO)(5)(apmsh)] [M = Cr; (1), Mo; (2), W; (3)], [Re(CO)(4)Br(apmsh)] (4) and [Mn(CO)(3)(apmsh)] (5) have been synthesized by the photochemical reaction of metal carbonyls [M(CO)(6)] (M = Cr, Mo and W), [Re(CO)(5)Br], and [Mn(CO)(3)Cp] with 2-hydroxyacetophenone methanesulfonylhydrazone (apmsh). The complexes have been characterized by elemental analysis, mass spectrometry, f.t.-i.r. and H-1 spectroscopy. Spectroscopic studies show that apmsh behaves as a monodentate ligand coordinating via the imine N donor atom in [M(CO)(5)(apmsh)] (1-4) and as a tridentate ligand in (5).
