Summary
This study details the crystal structure of a thiophene derivative, revealing a typical flip-type disorder in the thiophene ring. The structure features C-H···π hydrogen bonds and short S···O contacts, forming sheets and connecting adjacent ones.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Thiophene derivatives are common in various chemical applications.
- Understanding the crystal structure of these compounds is crucial for predicting their properties.
- Flip-type disorder is a known phenomenon in substituted thiophenes.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(6)H(6)OS.
- To analyze the molecular arrangement and intermolecular interactions.
- To compare the structure with related thiophene analogues.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
- Analysis of crystallographic data to identify disorder and intermolecular contacts.
- Comparative structural analysis with similar thiophene derivatives.
Main Results:
- The compound exhibits a flip-type disorder of the thiophene ring with an occupancy ratio of 0.848:0.152.
- The puckered thiophene ring is nearly coplanar with the acetyl substituent.
- Molecules form sheets via C-H···π hydrogen bonds, with adjacent sheets linked by S···O contacts.

02:23Structure and Nomenclature of Alcohols and Phenols
Overview
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.

01:26Thermal and Photochemical Electrocyclic Reactions: Overview
Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.
02:28Structure and Nomenclature of Ethers
Structure and Bonding
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.

02:36Acidity and Basicity of Alcohols and Phenols
Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.
01:18Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

03:02Organic Compounds
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...
