This study details the crystal structure of an organic acid (C18H12O3), revealing cyclic dimer hydrogen bonding and a 3D network formed by C-H...O interactions, crucial for understanding molecular assembly.

Area of Science:

  • Crystallography
  • Organic Chemistry
  • Supramolecular Chemistry

Background:

  • Understanding the intermolecular interactions of organic acids is vital for predicting their solid-state behavior.
  • Carboxylic acids are known to form characteristic hydrogen bonding motifs.

Purpose of the Study:

  • To elucidate the crystal structure and intermolecular interactions of the title organic acid (C18H12O3).
  • To analyze the hydrogen bonding and C-H...O interactions present in the crystal lattice.

Main Methods:

  • Single-crystal X-ray diffraction was employed to determine the crystal structure.
  • Analysis of hydrogen bond distances and network formation was performed.

Main Results:

  • The title acid (C18H12O3) crystallizes in the centrosymmetric space group C2/c.

  • Carboxyl groups form cyclic dimer hydrogen bonds with an Odonor-Oacceptor distance of 2.692 Å.
  • Extensive C-H...O interactions involving seven C-H groups and three O atoms create a 3D network.

    • Conclusions:

    • The crystal structure is stabilized by both strong carboxyl-based hydrogen bonds and weaker C-H...O interactions.
    • The ordered nature of the carboxylic hydrogen and oxygen atoms contributes to the defined network structure.
    • This detailed structural analysis provides insights into the packing and intermolecular forces governing the solid state of this organic acid.
