Zirconium(IV) N,N-dialkyldithiocarbamates of the type Cp2Zr(S2CNR2)Cl and (MeCp)2Zr(S2CNR2)Cl (R = Me, Et) have been prepared by reaction of dicyclopentadienyl zirconium(IV) dichloride and bismethylcyclopenadienyl zirconium(IV) dichloride with anhydrous sodium N,N-dialkyldithiocarbamates in refluxing dichloromethane. Molecular weight, conductance and infrared data demonstrate that these complexes are toohomeric nonelectrolytes in which the dithiocarbamate ligands are bidentate. Therefore, the zirconium(IV) atom may be assigned a coordination number 5. Proton nmr studies have also been carried out for these complexes.
