Researchers synthesized a novel compound, C(15)H(11)Cl(2)NO, from N-benzyl isatin. Structural analysis revealed molecular stacking driven by pi-pi, C-H...pi, and C-H...O interactions.
Area of Science:
- Organic Chemistry
- Crystallography
- Supramolecular Chemistry
Background:
- Isatin derivatives are known for diverse biological activities.
- Understanding intermolecular interactions is crucial for crystal engineering and materials science.
Purpose of the Study:
- To synthesize and characterize a novel N-benzyl isatin derivative.
- To elucidate the crystal structure and intermolecular interactions of the synthesized compound.
Main Methods:
- Chemical synthesis of the title compound from N-benzyl isatin.
- Single-crystal X-ray diffraction analysis to determine molecular and crystal structure.
Main Results:
- The compound C(15)H(11)Cl(2)NO was successfully synthesized.
- Crystal structure analysis revealed a packing arrangement of molecules in stacks along the c axis.
- Intramolecular interactions include pi-pi stacking and C-H...pi interactions within stacks.
- Intermolecular interactions between stacks are mediated by C-H...O bonds.
Conclusions:
- The synthesized N-benzyl isatin derivative exhibits a unique crystal packing.
- The observed intermolecular interactions dictate the supramolecular architecture.
- This study provides insights into the structure-property relationships of isatin derivatives.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
