Özet

Five new complexes, [M(CO)(5)(DTTT)] [M = Cr; 1, Mo; 2, W; 3], [Re(CO)(4)Br(DTTT)] (4) and [Mn(CO)(2)Cp(DTTT)] (5) have been synthesized by the photochemical reaction of metal carbonyls [M(CO)(6)] (M = Cr, Mo and W), [Re(CO)(5)Br], and [Mn(CO)(3)Cp] with 3,5-dimethyl-tetrahydro-2H-1,3,5-thiadiazine-2-thione (DTTT). The complexes have been characterized by elemental analysis, mass spectrometry, FTIR, H-1 and C-13{H-1} NMR spectroscopy. The spectroscopic studies show that DTTT behaves as a monodentate ligand coordinating via the sulfur (C=S) donor atom in 1-5. An X-ray diffraction study Of [W(CO)(5)(DTTT)] (3) confirms that the tungsten adopts a distorted octahedral geometry with local C-4nu symmetry. (C) 2003 Elsevier Science Ltd. All rights reserved.
