Potassium N,4-dichloro-benzene-sulfonamidate monohydrate

Area of Science:

• Crystal chemistry
• Solid-state chemistry

Background:

• Understanding the supramolecular assembly of salt hydrates is crucial for materials science.
• Potassium (K+) salts with organic anions offer diverse structural possibilities.

Purpose of the Study:
