Abstract:
Single crystals of 2-amino-4-nitro-1H-imidazol-3-ium chloride, C3H5N4O2 +·Cl-, were synthesized by slow evaporation and characterized by X-ray diffraction. The crystal structure features a planar imidazolium cation and a chloride anion, forming a three-dimensional supra-molecular network via N-H⋯Cl and N-H⋯O hydrogen bonds. Hirshfeld surface analysis reveals that O⋯H/H⋯O contacts (28.7%) and Cl⋯H/H⋯Cl inter-actions (24.2%) dominate the inter-molecular packing, with C⋯O/O⋯C contacts (5.1%) indicating significant C-H⋯O hydrogen-bonding contributions. Additional consolidation arises from van der Waals inter-actions (H⋯H, 13.4%), while π-π stacking remains negligible. The synergy of strong hydrogen bonds and weaker inter-actions underpins the robust supra-molecular architecture, providing insights into crystal engineering strategies for nitro-imidazole-based functional materials.

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
