Dithiochelates of the Bis(η-cyclopentadienyl)vanadium(IV) moiety. II. N,N-Dialkyldithiocarbamate and O,O'-dialkyldithiophosphate complexes

Abstract

Two series of complexes, believed to be of the forms (R1 = R2 = Me, Et, Pri, Bu and R1 = H, R2 = Me) and (R = Me, Et, C2H4Cl, Pr, Bu, n-C8H17) have been prepared. A large anion X was used to precipitate the green compounds, which are monomeric and 1 : 1 electrolytes in solution. Infrared, electronic and e.s.r. spectra are reported together with magnetic susceptibility measurements. The phosphorus hyperfine coupling observed in the dithiophosphates is discussed in the light of current models.
