Polarizability of some nickelocene derivatives from quantum mechanical delta function potentials – A comparative study

The atomic, bond and molecular polarizabilities of some nickelocene derivatives have been calculated using variational method and delta-function electronic wave functions. The bonding in nickelocenes has been investigated through the polarizability properties. The results from the nickelocenes derivatives have been correlated with the corresponding substituted benzenes. Scales have been presented, where the derivatives are classified in order of their polarization properties Common trends and patterns of behavior are recognized and discussed. The reported results are in good agreement with experimental values.
