Structural influences of the substituents of tridentate triazole-based ligands – more than just a minor role in the solid-state structure

Abstract

Abstract New triazole-based tridentate ligands were synthesized, and their crystal structures determined. Through comparison with the crystal structures of the starting materials and related published ligands, dependencies of intermolecular interactions based on the substitution patterns of the triazole motif were identified. In addition to π-stacking interactions, hydrogen bonding, and C–H···π interactions emerged as key players in intermolecular interactions. The observed variations in these interactions will aid in the design of platinum(II) complexes with specific properties.
