Özet

New complexes cis-[M(CO)(4)-DABRd] (M = Cr(I), Mo(II) and fac-[M(CO)(3)-SAT] (M = Cr(III), Mo(IV)) have been synthesized by the photochemical reactions of cis-[(eta(4)-NBD)M(CO)(4)] (NBD = norbornadiene; M = Cr, Mo) with 5-(4-dimethylaminobenzylidene) rhodanine (DABRd) and saticylidene-3-amino1,2,4-triazole (SAT) ligands and characterized by elemental analysis, FT-IR and H-1 NMR spectroscopy, and mass spectrometry. The spectroscopic studies show that the DABRd ligand acts as a bidentate ligand coordinating via both NH-(S)C=S sulfur donor atoms in I and II and SAT ligand behaves as a tridentate ligand coordinating via its all imine nitrogen -C=N- donor atoms in III and IV to the metal center.
