Öğe Photochemical reactions of metal carbonyls [M(CO)(6) (M=Cr, Mo, W), Re(CO)(5)Br, Mn(CO)(3)CP] with 3,5-dimethyl-tetrahydro-2H-1,3,5-thiadiazine-2-thione (DTTT) and the crystal structure of [W(CO)(5)(DTTT)](Pergamon-Elsevier Science Ltd, 2003) Sert, S; Ercag, A; Senturk, OS; Sterenberg, BT; Udachin, KA; Ozdemir, U; Sarikahya, FUFive 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.

The complexes have been characterized by elemental analysis, mass spectroscopy (EI), FT-IR and P-31{H-1} NMR spectrometry. The spectroscopic studies suggest cis-chelate bidentate coordination of the ligand in fac-[Re(CO)(3)Br{R2P(S)P(S)R-2}] and cis-bridging bidentate coordination of the ligand between two metals in [Re-2(CO)(8)Br-2{cis-mu-R2P(S)P(S)R-2}] (R = Me, Et, Pr-n, Bu-n, Ph).
