Özet

The hitherto unknown complexes, [M-2(CO)(6)-(mu-CO)(mu-L)], [M = Cr; 1, Mo; 2, W; 3] and [M-2(CO)(6)-(mu-CO)(mu-L ')], [M = Cr; 4, Mo; 5, W; 6] have been synthesized by the photochemical reactions of photogenerated intermediate, M(CO)(5)THF (M = Cr, Mo, W) with thio Schiff base ligands, N,N '-bis(2-aminothiophenol)-1,4-bis(2-carboxaldehydephenoxy)butane (H2L) and N,N '-bis(2-aminothiophenol)- 1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane (H2L '). The complexes have been characterized by elemental analysis, LC-mass spectrometry, magnetic studies, FT-IR and H-1 NMR spectroscopy. The spectroscopic studies show that H2L and H2L ' ligands are converted to benzothiazole derivatives, L and L ' after UV irradiation and coordinated to the central metal as bridging ligands via the central azomethine nitrogen and sulphur atoms in 1-6.
