Özet

The hitherto unknown complexes, cis-[M(CO)2(4-H2L')], [M = Cr; 1, Mo; 2, W; 3] and cis-[M(CO)2(4-H2L)], [M = Cr; 4, Mo; 5, W; 6] have been synthesized by the photochemical reactions of photogenerated intermediate, M(CO)5THF (M = Cr, Mo, W) with salen type Schiff base ligands, N,N'-bis(salicylidene)-1,4-diaminobutane (H2L') and N,N'-bis(2-hydroxy-3-methoxybenzylidene)ethylenediamine (H2L). The complexes have been characterized by elemental analyses, LC- mass spectrometry, magnetic studies, FTIR and 1H NMR spectroscopy. The spectroscopic studies show that H2L' and H2L ligands coordinated to the central metal as tetradentate ligands coordinating via the central azomethine nitrogens (C = N) and phenolic oxygen atoms in complexes 1-3 and via aromatic methoxy and phenolic oxygen atoms in complexes 4-6, respectively.
