This study reveals the molecular structure of C(21)H(44)O(2), detailing its all-trans hydrocarbon skeleton and hydroxyl group orientations. Crystal packing resembles smectic A liquid crystals, differing from even-numbered carbon chain homologues.

Area of Science:

  • Molecular Crystallography
  • Organic Chemistry
  • Materials Science

Background:

  • Understanding the relationship between molecular structure and crystal packing is crucial in materials science.
  • Long-chain aliphatic compounds exhibit diverse packing behaviors influenced by chain length and terminal groups.

Purpose of the Study:

  • To elucidate the detailed molecular and crystal structure of the title compound, C(21)H(44)O(2).
  • To compare its packing arrangement with homologous compounds possessing varying carbon chain lengths.

Main Methods:

  • Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
  • Conformational analysis of the hydrocarbon skeleton and terminal hydroxyl groups was performed.

Main Results:

  • The hydrocarbon skeleton of C(21)H(44)O(2) adopts an all-trans conformation.
  • One terminal hydroxyl group is trans, and the other is gauche relative to the skeleton.
  • Molecules are arranged parallel to the b axis, forming layers with a thickness of b/2, mimicking smectic A liquid crystal phases.
  • Observed packing differs from even-numbered carbon chain homologues but is similar to odd-numbered ones.

Conclusions:

  • The specific conformation and hydroxyl group orientations dictate the observed crystal packing.
  • The packing behavior of C(21)H(44)O(2) aligns with trends seen in odd-numbered long-chain aliphatic compounds.
  • This study provides insights into structure-property relationships in crystalline organic materials.
