Intermolecular perturbation in the self‑assembly of melamine

A theoretical study has been conducted on a set of supramolecular complexes based on 1,3,5-triazine-2,4,6- triamine, or melamine (M), with cyanuric acid (CA), trithiocyanuric acid (TCA), and two mono-substituted derivatives of CA with chlorine (CACl) and bromine (CABr). The study was carried ou...
