Abstract

Abstract Crystal structures of 2, 4, 6-tris (2-halophenoxy)-1, 3, 5-triazines (halo= fluoro, chloro, bromo, iodo; 2-XPOT) are discussed in the background of 3-halophenoxy (3-XPOT) and 4-halophenoxy (4-XPOT) structures. Among inter-halogen interactions, the electrostatic L-shaped type II interactions are generally shorter than the inversion-related type I geometry in 2-halo compounds. π-Stacking of triazine rings at van der Waals separation (∼ 3.5 Å) ...
