2-Methyl-3-(3-methyl-phen-yl)acrylic acid.

Area of Science:

• Crystallography
• Supramolecular Chemistry

Background:

• Understanding molecular interactions is crucial for materials science.
• Crystal structure analysis provides insights into intermolecular forces.

Purpose of the Study:

• To elucidate the crystal structure of C(11)H(12)O(2).
• To identify and characterize the intermolecular interactions governing crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of hydrogen bonds (O-H⋯O, C-H⋯O) and π-π interactions was performed.

Main Results:

• The crystal structure features dimers formed by O-H⋯O hydrogen bonds.
• Dimers are linked by C-H⋯O hydrogen bonds, creating five-membered rings.
• Two distinct π-π interactions with perpendicular distances of 3.006 and 3.396 Å were observed, alongside C-H⋯π and C-O⋯π interactions.

Conclusions:

• The crystal packing of C(11)H(12)O(2) is dictated by a combination of hydrogen bonding and π-π stacking.
• These interactions define the supramolecular architecture of the compound.
