ELECTROTOPOLOGICAL STATE STUDIES OF COPPER(II) COMPLEXES WITH alpha-AMINOACIDATES

Descriptor combinations, consisting of the electrotopological state (E-state) indexes of some skeletal groups, the first-order ¹chi molecular connectivity index and the logarithm of the statistical factor, are employed to describe the second stepwise formation constants of binary and ternary copper(...
