6-Methyl-pyridine-2(1H)-thione.
Summary
This study reveals that pyridine-thione derivatives exist in the thione form, not the mercaptan form. Crystal structure analysis shows molecules forming dimers via hydrogen bonds, creating a 3D network.
Area of Science:
- Crystallography and Molecular Structure
- Organic Chemistry
- Supramolecular Chemistry
Background:
- Pyridine-thione derivatives are organic compounds with potential applications in various chemical fields.
- Understanding the tautomeric forms (thione vs. mercaptan) is crucial for predicting chemical behavior and reactivity.
- Intermolecular interactions play a significant role in the self-assembly and solid-state properties of organic molecules.
Purpose of the Study:
- To determine the specific molecular structure and tautomeric form of a pyridine-thione derivative.
- To investigate the intermolecular interactions and crystal packing of the compound.
- To elucidate the formation of supramolecular architectures in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to analyze the crystal structure.
- Analysis of bond lengths and angles confirmed the thione tautomer.
- Identification of hydrogen bonds and other non-covalent interactions through crystallographic data.
Main Results:
- The asymmetric unit contains two unique molecules of the pyridine-thione derivative (C(6)H(7)NS).
- Both molecules adopt the thione tautomeric form, with planar ring structures.
- Centrosymmetric cyclic dimers are formed via intermolecular N-H⋯S hydrogen bonds, further organized into a 3D network by C-H(methyl)⋯S interactions.
Conclusions:
- The pyridine-thione derivative predominantly exists in the thione form in the solid state.
- Specific hydrogen bonding and C-H⋯S interactions dictate the formation of dimers and a 3D supramolecular network.
- The findings provide insights into the structural characteristics and self-assembly behavior of this class of compounds.

01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom, respectively.
02:26Preparation and Reactions of Sulfides
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
02:17Structure and Nomenclature of Thiols and Sulfides
Thiols and sulfides are sulfur analogs of alcohols and ethers, respectively, where the sulfur atom takes the place of the oxygen atom. Thus, thiols are generally represented as RSH, where R is an alkyl substituent and —SH is the functional group. On the other hand, in sulfides, the central sulfur atom is bonded to two hydrocarbon groups on either side. Depending upon the type of group, sulfides can be either symmetrical or asymmetrical. Both thiols and sulfides display a bent geometry, similar...
01:25Basicity of Heterocyclic Aromatic Amines
Heterocyclic amines, where the N atom is a part of an alicyclic system, are similar in basicity to alkylamines. Interestingly, the heterocyclic amine having a nitrogen atom as part of an aromatic ring has much less basicity than its corresponding alicyclic counterpart. For this reason, as presented in Figure 1, piperidine (pKb = 2.8) is significantly more basic than pyridine (pKb = 8.8).
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.

02:33Preparation and Reactions of Thiols
Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.
