Bis-η5-cyclopentadienyl and Bis-η5-methylcyclopentadienylN,N-dialkyldithiocarbamato(chloro)titanium(IV) compounds

SummaryTitanium(IV)N,N-dialkyldithiocarbamates of the type η5-Cp2Ti (S2CNR2)Cl and (η5-MeCp)2Ti(S2CNR2)Cl (R = Me, Et and i-Pr) have been prepared by the reaction of di--cyclopentadienyldichlorotitanium(IV) and bis-n-methylcyclopentadienyldichlorotitanium(IV) with sodium salts of dithiocarbamic acids in refluxing dichloromethane. Molecular weight, conductance and i.r. studies show these complexes to be monomeric nonelectrolytes in which the dithiocarbamate ligands are bidentate. Therefore, pentacoordination may be assigned to titanium(IV) atom in all six complexes. Electronic and proton n.m.r. studies spectra have also been recorded for the complexes.

Synthesis and Characterisation of Bis(π-cyclopentadienyl) N-aryl Substituted Dithiocarbamato Chloro Titanium (IV) Compounds

Abstract Bis(π-cyclopentadienyl) N-aryl substituted dithio-carbamato chloro titanium(IV) compounds have been synthesised by the reaction of bis(π-cyclopentadienyl) titanium(IV) dichloride with ammonium (N-aryl substituted) dithiocarbamates in refluxing dichloromethane. Molecular weight, conductance and infrared studies point out that these complexes are monomeric non-electrolytes in which the dithiocarbamate ligands are bidentate. Therefore, a coordination number of ‘5’ may be assigned to the titanium(IV) atom in all the twelve complexes. Electronic spectra have also been obtained for these complexes

Bis(π-cyclopentadienyl) BIS(N-aryl substituted dithiocarbamato) titanium(IV) complexes

Abstract Bis(π-cyclopentadienyl) bis(N-aryl substituted dithiocarbamato) titanium(IV) have been prepared by the reaction of bis(π-cyclopentadienyl) titanium(IV) dichloride with ammonium (N-aryl substituted) dithiocarbamates in aqueous medium. Conductance, IR and molecular weight studies show that these complexes are monomeric non-electrolytes in which the dithiocarbamate ligands are bidentate.
