Resumen
This paper discloses the synthesis of 1,3,5-Tris(4-bromophenyl)-1,3,5-triazin-2,4,6-trione·CHCl3, (Cy·CHCl3). The title compound was purified by recrystallization in chloroform. Structural and crystalline analysis reveals that Cy·CHCl3 crystallizes in the trigonal space group R3c. The high symmetry is due to the finding in the crystal of the existence of a π-halogen intermolecular interaction between the title compound and one chloroform molecule as lattice solvent, forming a honeycomb-shape pattern when the isocyanurate core centroids are joined in the packing diagram. Also, crystal structure of Cy·CHCl3 reveals that cell packing is stabilized by hydrogen bond interactions. All interactions were verifying through Hirshfeld surface analyses.
