Abstract

Combined kinetic and equilibrium studies of the complexation of the ligand N,N′-bis[2-(2-pyridyl)methyl]pyridine-2,6-dicarboxamide with copper(ii) and nickel(ii), examined conjointly employing advanced chemometric methods, provides elucidation of speciation and formation pathways in solution for complexes such as M₂L₂ and M₂L₃ helicates, respectively.
