Space-group revision for 4-formylphenylboronic acid

Area of Science:

• Crystallography
• Solid-state chemistry
• Materials science

Background:

• Accurate crystal structure determination is crucial for understanding material properties.
• Previous structural data for C7H7BO3 suggested a P1 space group, potentially leading to misinterpretations.

Purpose of the Study:

• To accurately determine the crystal space group of C7H7BO3.
• To investigate potential disorder within the formyl and boronic acid groups.
• To refine understanding of the molecular arrangement and symmetry in the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction analysis.
• Structure refinement using crystallographic software.
• Analysis of molecular symmetry and atomic positions.

Main Results:

• The correct space group for C7H7BO3 was identified as Cc, differing from the previously reported P1.
• No significant disorder was observed in the formyl group or the hydrogen atoms of the boronic acid group.
• Molecules are situated on approximate twofold axes and related by approximate centers of symmetry.

Conclusions:

• The corrected Cc space group provides a more accurate representation of the C7H7BO3 crystal structure.
• The absence of disorder simplifies the understanding of intermolecular interactions and packing.
• This precise structural data is essential for further studies on the chemical and physical properties of C7H7BO3.
