This study details the crystal structure of C(16)H(16)N(2)O(4), revealing an inversion center and intramolecular hydrogen bonds forming an S(6) ring. Molecules further assemble into infinite chains through intermolecular N-H⋯O hydrogen bonds in the crystal lattice.
Area of Science:
- Crystallography
- Supramolecular Chemistry
- Organic Chemistry
Background:
- Understanding molecular arrangement in crystals is crucial for predicting material properties.
- Hydrogen bonding plays a key role in the self-assembly of molecules.
- The specific compound C(16)H(16)N(2)O(4) has not been previously characterized structurally.
Purpose of the Study:
- To elucidate the crystal structure of C(16)H(16)N(2)O(4).
- To identify and characterize hydrogen bonding interactions within the crystal.
- To describe the supramolecular architecture formed by the molecules.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- The crystal structure was analyzed to identify symmetry elements, including inversion centers.
- Hydrogen bond analysis was performed to characterize both intramolecular and intermolecular interactions.
Main Results:
- The asymmetric unit contains a half-molecule, with the full molecule generated by an inversion center.
- An intramolecular O-H⋯O hydrogen bond was observed, forming a six-membered S(6) ring motif.
- Intermolecular N-H⋯O hydrogen bonds link molecules into infinite chains along the [1-10] direction.
Conclusions:
- The crystal structure of C(16)H(16)N(2)O(4) is fully described, highlighting the role of symmetry and hydrogen bonding.
- The observed hydrogen bonding network dictates the formation of one-dimensional supramolecular chains.
- This structural information provides a foundation for further studies on the physical and chemical properties of this compound.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
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...
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
