Suitability of the Topological Index W^1/3 for Estimation of the Stability Constants of Coordination Compounds

Sa？etak The cubic root of the Wiener number, W1/3, was correlated to stability constants of copper(II) chelates with naturally occurring amino acids and their N-alkylated derivatives. The results were compared to similar correlations obtained by other topological indices (W and Randi？’s connectivity indices). W1/3 yielded the best result in four out of nine cases, and in all cases yielded better results than topological index W
