Prediction of Stability Constants of Zinc(II) Complexes with 2-aminobenzamide and Amino Acids

摘要

We developed a model for the stability (log beta(ZnLB)) of Zn2+ mixed complexes (N = 16) with 2-aminobenzamide (L) and four amino acids (B) glycine, alanine, valine, and phenylalanine at 300, 310, 320, and 330 K. The model based on the quadratic regression function of the molecular valence connectivity index of the third order, (3)chi(v), yielded S.E. = 0.02. We also developed an overall model for K-1, K-2 and beta(ZnLB) of the same system at all of the four temperatures (N = 48). This model yielded S.E. = 0.05.
