This study details the molecular structure of C(6)H(10)O(3)S(2), revealing a planar carbon atom bonded to oxygen and sulfur. Dimers form via hydrogen bonding, showcasing distinct C-S bond lengths.
Area of Science:
- Crystallography
- Chemical structure analysis
Background:
- Understanding molecular geometry and intermolecular forces is crucial in chemistry.
- Sulfur-containing organic compounds exhibit diverse structural motifs and reactivity.
Purpose of the Study:
- To elucidate the crystal structure and bonding characteristics of the title compound C(6)H(10)O(3)S(2).
- To investigate the intermolecular interactions, specifically hydrogen bonding, in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional molecular structure.
- Analysis of bond lengths, bond angles, and intermolecular contacts was performed.
Main Results:
- The crystal structure reveals a planar carbon atom bonded to one oxygen and two sulfur atoms.
- A distinct difference in C-S single and double bond lengths was observed.
- Two molecules associate via an O-H⋯O hydrogen bond around a center of inversion, forming a dimer.
Conclusions:
- The compound C(6)H(10)O(3)S(2) exhibits specific structural features including a planar C atom and variable C-S bond lengths.
- Intermolecular hydrogen bonding plays a significant role in the self-assembly of these molecules into dimers in the crystal lattice.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
