The study investigates crystallization conditions for metal-organic frameworks (MOFs) using two complexes: zinc bromide and zinc chloride derivatives of a triazine derivative.
The bromide structure underwent a phase transition when cooled from 299K to 100K, changing from orthorhombic to monoclinic symmetry, which involved conformational changes.
Key interactions stabilizing the crystal packing include hydrogen bonds, aromatic π-stacking, and various intramolecular contacts involving halide ligands and nitrogen atoms.
