    Structure:
    crystalline
    Name:
    C.I. Pigment Red 178
    Pure structure:
    yes
    Description:
    Assessed as crystalline based on TEM pictures.
    It is well known in the field of Pigments that powder X-Ray diffraction mesurements of very fine crystals cannot be used to properly define the crystal system and/or Bravais lattice due to signal broadening.
