This study details the crystal structure of a twisted molecule, C12H10N4O, featuring a 1,2,3-triazole ring. Attractive intermolecular interactions and Hirshfeld surface analysis reveal key bonding contributions in its solid-state architecture.
Area of Science:
- Crystallography
- Molecular structure analysis
- Supramolecular chemistry
Background:
- 1,2,3-triazole derivatives are important scaffolds in medicinal chemistry and materials science.
- Understanding the solid-state packing and intermolecular interactions is crucial for predicting material properties.
Purpose of the Study:
- To elucidate the crystal structure and supramolecular assembly of a novel C12H10N4O compound.
- To analyze the nature and contribution of intermolecular interactions within the crystal lattice.
- To investigate the electronic and steric factors influencing the molecule's conformation.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Non-covalent interaction plots were utilized to analyze attractive forces.
- Hirshfeld surface analysis was performed to quantify the contributions of different intermolecular contacts.
Main Results:
- The compound C12H10N4O exhibits a twisted molecular geometry with a central 1,2,3-triazole ring.
- Significant intermolecular interactions, including carbonyl-π, cyano-π, and π-π stacking, stabilize the crystal structure.
- Hirshfeld surface analysis indicated dominant H⋯H (35.9%) and N⋯H (26.2%) contacts, with notable contributions from O⋯H, C⋯H, C⋯C, and C⋯N interactions.
Conclusions:
- The detailed structural analysis provides insights into the packing preferences and intermolecular forces governing the solid state of this triazole derivative.
- The identified attractive interactions are key to the formation of the observed three-dimensional crystal architecture.
- This study contributes to the understanding of structure-property relationships in N-heterocyclic compounds.

Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
