Polymorphism and Hirshfeld surface analysis of tetra-oxa[2]perfluoro-arene[2]triazine.

ABSTRACT: The title compound, tetra-oxa[2]perfluoro-arene[2]triazine (C₂₀H₆F₈N₆O₆), composed of two tetra-fluoro-phenyl-ene and two triazine moieties connected by four oxygen atoms, was crystallized via slow evaporation of a di-chloro-methane solution, yielding two polymorphs: block- (I) and plate-shaped (II) crystals. Polymorph I (triclinic, P1, V = 516 ų at 173 K) was previously reported by Yang et al. [(2015. Org. Lett. 15, 4414-4417] whereas the newly identified polymorph II (triclinic, P1, V = 1085 ų at 100 K) shares the same space group but has a unit-cell volume twice as large, accommodating two symmetrically distinct mol-ecules,
