N,N'-(1,4-Phenyl-ene)bis-(4-chloro-butanamide)
This study details the crystal structure of a molecule with the formula C(14)H(18)Cl(2)N(2)O(2). Researchers observed specific molecular conformations and intermolecular hydrogen bonding in the solid state.
Area of Science:
- Crystallography and Molecular Structure
Background:
- Understanding the solid-state behavior of organic molecules is crucial for predicting their physical and chemical properties.
- The specific arrangement of atoms and intermolecular forces dictate crystal packing and macroscopic characteristics.
Purpose of the Study:
- To elucidate the crystal structure of the title molecule, C(14)H(18)Cl(2)N(2)O(2).
- To characterize the molecular conformation and intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
- Analysis of crystallographic data to identify molecular symmetry elements and conformation.
Main Results:
- The molecule C(14)H(18)Cl(2)N(2)O(2) was found to reside on a crystallographic inversion center.
- Each 4-chloro-butanamide group adopts an anti-staggered conformation.
- Infinite ribbons were formed through N-H⋯O hydrogen bonding between adjacent molecules, aligned parallel to the a axis.
Conclusions:
- The crystal structure reveals a specific arrangement of the C(14)H(18)Cl(2)N(2)O(2) molecule in the solid state.
- Intermolecular N-H⋯O hydrogen bonds play a significant role in the self-assembly of these molecules into extended ribbon structures.

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...
