CORNWELL, Edward; LARRAZABAL, Guillermo  e  DECINTI, Antonio. Electropological State Studies of Nickel(II) Complexes with α-Aminoacidates. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.4, pp.247-250. ISSN 0583-7693.

The electrotopological states of a series of α-aminoacids are calculated. The resulting indices are correlated with the logarithms of the stepwise formation constants K₁ and K₂ of the respective nickel(II)-aminoacidate complexes by using multiple linear regression analysis. Good correlation equations are obtained for both stepwise formation constant series. A reduction in the number of descriptors by combining the electrotopological states of the potential ligands groups with first- order ¹χ^v molecular connectivity indices is also attempted.
