This study details the crystal structure of a potassium salt of N-bromo-2-nitro-benzene-sulfonamidate hydrate. The potassium ion exhibits hepta-coordination, and the structure is stabilized by hydrogen bonds forming polymeric layers.
Area of Science:
- Crystallography
- Inorganic Chemistry
- Organic Chemistry
Background:
- Understanding the coordination chemistry and crystal packing of sulfonamidate salts is crucial for materials science.
- Bromo-nitro-benzene derivatives are important intermediates in organic synthesis and have potential applications.
Purpose of the Study:
- To elucidate the crystal structure of the potassium salt of N-bromo-2-nitro-benzene-sulfonamidate hydrate.
- To analyze the coordination environment of the potassium ion and the bonding characteristics within the molecule.
- To investigate the intermolecular interactions stabilizing the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
- Analysis of bond lengths, bond angles, and coordination numbers provided insights into the molecular geometry.
- Identification of hydrogen bonding networks and their role in crystal structure formation.
Main Results:
- The potassium ion is hepta-coordinated, interacting with water molecules and the sulfonamidate anion.
- The S-N bond distance suggests a double bond character, indicating specific electronic properties.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
