Photochemical Reaction of Metal Carbonyls [M(CO)6 (M=Cr,Mo,W)] with 2-acetyl-5-chlorothiophenemethanesulfonylhydrazone

The new complexes, [M(CO) 5 (msh4)] (Cr(1), Mo(2), W(3)), have been synthesized by the photochemical reaction of metal carbonyls with 2-acetyl-5-chlorothiophenemethanesulfonylhydrazone( msh4 ) .The structure of these complexes has been investigated by using elemental analyses; FT-IR; EI-MS and 1 H NMR spectrometric methods. According to all spectroscopic data, msh4 is monodaentate and coordinate via thiophene ring sulfur.
