The crystal structure of C9H8O3 reveals an almost planar molecular skeleton. Molecules form a 2D network via weak hydrogen bonds in the crystal lattice.
Area of Science:
- Crystallography
- Molecular structure determination
Background:
- Understanding molecular arrangements in crystals is key to predicting material properties.
- The title compound, C9H8O3, was synthesized and its solid-state structure investigated.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C9H8O3.
- To analyze the intermolecular interactions and packing in the crystal.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular contacts was performed.
Main Results:
- The molecular skeleton of C9H8O3 was found to be nearly planar, with a root-mean-square deviation of 0.010(2) Å.
- Weak C-H⋯O hydrogen bonds were identified as the primary intermolecular forces.
- These interactions organize the molecules into a two-dimensional network parallel to the ac plane.
Conclusions:
- The crystal structure provides fundamental insights into the solid-state behavior of C9H8O3.
- The observed hydrogen bonding network influences the compound's packing and potential properties.

Five-Membered Heterocyclic Aromatic Compounds: Overview
Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
