Organometallic Vanadium in Compounds

Organometallic Vanadium (in) Compounds. A wide range of ji-cyclopentadienyl dicarboxylates has been prepared and their magnetic properties have been interpreted on the basis of monomeric units or dimers of the [(7c-Cp)-V(02CCF3)2]2 type. This latter structure has been confirmed for bis-(7c-cyclopentadienyl)vanadium(iii) di-a-furancar boxy late by X-ray diffraction methods the four bridging carboxylato-groups span a V — V distance of 

Polarographic reduction of [(7u-Cp)2VS2CNR2] (R2 = Mcj, Et2, Prjj, Bu2, or MeH) has been shown to yield the corresponding neutral V complex. These molecules are susceptible to dissociation, releasing free S2CNR2 ions, a process which is enhanced by the presence of oxygen.
