Summary
This study details the crystal structure of a compound (C11H12N2O6), revealing two distinct molecular conformations. These molecules form chains through hydrogen bonds in the crystal lattice.
Area of Science:
- Crystallography
- Molecular structure determination

Background:
- Understanding molecular conformation is crucial in chemistry and materials science.
- Crystal structure analysis provides insights into intermolecular interactions and solid-state properties.
Purpose of the Study:
- To elucidate the crystal structure of the title compound C(11)H(12)N(2)O(6).
- To analyze the conformational differences between independent molecules in the asymmetric unit.
- To investigate the hydrogen bonding network and its role in crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- Conformational analysis was performed by examining dihedral angles.
- Intermolecular interactions were identified through hydrogen bond analysis.
Main Results:
- The title compound, C(11)H(12)N(2)O(6), crystallizes with two independent molecules in the asymmetric unit.
- The dihedral angles between the amide plane and the benzene ring indicate slight conformational variations (19.5(3)° and 23.4(3)°).
- A chain structure along the a axis is formed by alternating independent molecules linked via N-H⋯O hydrogen bonds.
Conclusions:
- The crystal structure reveals nuanced conformational diversity within the asymmetric unit.

Carboxylic acids react with diazomethane in an ether solvent via alkylation at the carboxylate oxygen atom to give methyl esters of the corresponding acid with excellent yields.
01:11Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
Naming Amides
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.

01:13meta-Directing Deactivators: –NO2, –CN, –CHO, –CO2R, –COR, –CO2H
All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for the...
01:202° Amines to N-Nitrosamines: Reaction with NaNO2
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.
01:17Phase II Reactions: Methylation Reactions
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

01:20Electrophilic Aromatic Substitution: Nitration of Benzene
The nitration of benzene is an example of an electrophilic aromatic substitution reaction. It involves the formation of a very powerful electrophile, the nitronium ion, which is linear in shape. The reaction occurs through the interaction of two strong acids, sulfuric and nitric acid.
