Polarizability of some cobaltocene, nickelocene, derivatives using empirical approach.

The molecular polarizabilities of 20 cobaltocene derivatives have been calculated using a new empirical approach based on the square of the sum of the atomic hybrid components (ahc), namely α (ahc) = 4 N (Σ A τ A) (Å)3. Where the summation proceeds over all atoms A=1,2,3, upto N, and N is the total number of electrons in the molecule. Common trends and patterns of behavior are recognized and discussed. The results have been compared with those calculated by using Lippincott & Stutman's method. [ABSTRACT FROM AUTHOR]
