- 中文摘要: Bis (..-cyclopentaienyl) Nm N-disubstituted dithiocarbamato chloro oxotungsten (VI) complexes of the type ..-Cp2WO(S2CNR2)Cl and ..-Cp2WO(S2CNRR′)Cl (where R=Me, Et and i-Pr and R′=Cyhx) have been prepared by the reaction of bis (..-cyclopentadienyl) oxotungsten (VI) dichloride with sodium salts of dithiocarbamic acids in refluxing tetrahydrofuran. Infrared spectral studies demonstrate that in these complexes dithiocarbamate ligands are bidentate. Therefore, tungsten (VI) atom may be assigned a coordination number 6 in all these complexes. Elemental analyses of these compounds have also been carried out. Electronic spectra have been recorded for all the six complexes.
