N-(3,4-Dichloro-phen-yl)maleamic acid
Summary
This study details the crystal structure of a C(10)H(7)Cl(2)NO(3) compound. Molecules are stabilized by intramolecular hydrogen bonds and form chains and sheets through intermolecular interactions.
Area of Science:
- Crystallography
- Organic Chemistry
- Supramolecular Chemistry
Background:
- Understanding molecular interactions is key in crystal engineering.
- Maleamic acid derivatives exhibit diverse hydrogen bonding patterns.
- Halogen bonding influences crystal packing and material properties.
Purpose of the Study:
- To elucidate the crystal structure of the title compound C(10)H(7)Cl(2)NO(3).
- To investigate the role of intramolecular and intermolecular interactions in stabilizing the crystal lattice.
- To characterize the hydrogen bonding and halogen bonding networks present.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of hydrogen bond distances and angles.
- Identification and analysis of short intermolecular contacts, including C-Cl⋯O interactions.
Main Results:
- The asymmetric unit contains two unique molecules of C(10)H(7)Cl(2)NO(3).
- Both molecules feature an intramolecular O-H⋯O hydrogen bond within the maleamic unit.
- Intermolecular N-H⋯O hydrogen bonds form chains, further assembled into sheets by C-Cl⋯O=C contacts.
Conclusions:
- The crystal structure is stabilized by a combination of intra- and intermolecular hydrogen bonds.
- Short C-Cl⋯O=C contacts play a significant role in the sheet formation.
- This study provides insights into the supramolecular assembly of halogenated maleamic acid derivatives.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
Naming Acid Halides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.

IUPAC Nomenclature of Aldehydes
Aldehydes are named based on the systematic nomenclature rules set by the IUPAC. For acyclic aldehydes, the longest carbon chain containing the aldehydic (–CHO) group is considered the parent chain. The aldehyde is named by replacing the last letter “e” in the hydrocarbon name with “al”. For instance, a simple, seven-carbon-membered acyclic aldehyde is called heptanal, derived from heptane. The carbon chain is numbered starting from the aldehydic carbon, although the aldehydic carbon’s locant...
Alkylation of β-Diester Enolates: Malonic Ester Synthesis
Malonic ester synthesis is a method to obtain α substituted carboxylic acids from ꞵ-diesters such as diethyl malonate and alkyl halides.
Loss of Carboxy Group as CO2: Decarboxylation of Malonic Acid Derivatives
Just like β-keto acids—which upon thermal decarboxylation form ketones—β-dicarboxylic acids undergo decarboxylation to generate monocarboxylic acids with the liberation of carbon dioxide.
Diazonium Group Substitution: –OH and –H
Nitrous acid, a weak acid, is prepared in situ via the reaction of sodium nitrite with a strong acid under cold conditions. This nitrous acid prepared in situ reacts with primary arylamines to form arenediazonium salts. Such reactions are known as diazotization reactions. As shown in Figure 1, the formation of arenediazonium salts begins with the decomposition of nitrous acid in an acidic solution to give nitrosonium ions.
Nomenclature of Primary Amines
Primary, secondary, and tertiary amines are compounds consisting of one, two, and three alkyl groups connected to the amino group (–NH2), respectively. As depicted in Figure 1, the common name of the primary amines is obtained by adding the suffix -amine to the alkyl substituent attached to the amino group as the corresponding alkylamine.
