By reaction of V(CO)₆ with aromatic compounds at 35° some new complex cations [V(CO)₄C₆H_6-nR_n]⁺ have been prepared as the hexacarbonylvanadates. With highly substituted methylbenzenes the yields are 20-53%. The complex cation is characterized by two main infrared CO stretching bands, whose position depends on the nature and the number of the substituents R_n. In this series of compounds a correlation has been found to exist between the shift from the benzene derivative of the cationic CO stretching vibrations and Δμ_Rn, the group contribution to the dipole moment, calculated from the literature data for Cr(CO)₃arene complexes.
