Five new complexes, [M(CO)(5)(apesh)] [M = Cr; (1), Mo; (2), W; (3)], [Re(CO)(4) Br(apesh)] (4) and [Mn(CO)(3)(apesh)] (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-hydroxyacetophenone ethanesulfonylhydrazone (apesh). The complexes have been characterized by elemental analysis, mass spectrometry, FT-IR, H-1 NMR spectroscopy. The spectroscopic studies show that apesh behaves as a monodentate ligand coordinating via imine N donor atom in (1)-(4) and as tridentate ligand in (5). (C) 2003 Elsevier Science B.V.
