Özet

The new complexes, [(mu-CO)(2)Cr-2(4-H2L)(2)], 1; [(mu-CO)M-2(CO)(2)(eta(4)-H2L)(2)], [M = Mo; 2, W; 3]; [(mu-CO)(2)Cr-2(eta(4)-H2L')(2)], 4, and [(mu-CO)M-2(CO)(2)(eta(4)-H2L')(2)], [M = Mo; 5, W; 6] have been synthesized by the photochemical reactions of photogenerated intermediate, M(CO)(5)THF (M = Cr, Mo, W) with two oxygen and nitrogen donor Schiff base ligands, N,N'-bis(2-hydroxynaphtalin-1-carbaldehydene)-1,2-bis(p-aminophenoxy)ethane (H2L) and N,N'-bis(2-hydroxynaphtalin-1-carbalde-hydene)-1,4-bis(p-aminophenoxy)butane (H2L'). The complexes have been characterized by elemental analyses, LC-mass spectrometry, magnetic studies, FTIR, and H-1-NMR spectroscopy. The spectroscopic studies show that H2L and H2L' ligands are coordinated to the central metal as tetradentate ligands coordinating via their imine N and O donor atoms in (1-6).
