The crystal structure of hexamethylenetetraminium 2,4,6-trinitrophenolate reveals bifurcated hydrogen bonds. These interactions, along with C-H...O and C-H...pi bonds, stabilize the sheet-like arrangement of ions.

Area of Science:

  • Crystal Engineering
  • Supramolecular Chemistry
  • Materials Science

Background:

  • Understanding intermolecular interactions is crucial for designing novel materials.
  • The study of ionic adducts provides insights into crystal packing and stability.
  • Hexamethylenetetramine derivatives and picrate anions are common motifs in crystal engineering.

Purpose of the Study:

  • To characterize the crystal structure of the 1:1 ionic adduct of hexamethylenetetraminium and 2,4,6-trinitrophenolate.
  • To investigate the role of hydrogen bonding and other non-covalent interactions in stabilizing the crystal lattice.
  • To elucidate the supramolecular assembly of cations and anions in the solid state.

Main Methods:

  • Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
