Abstract:
The mol-ecular structure of the title compound, C13H7Cl3OS, consists of a 2,5- di-chloro-thio-phene ring and a 2-chloro-phenyl ring linked via a prop-2-en-1-one spacer. The dihedral angle between the 2,5-di-chloro-thio-phene and 2-chloro-phenyl rings is 9.69 (12)°. The mol-ecule has an E configuration about the C=C bond and the carbonyl group is syn with respect to the C=C bond. The mol-ecular conformation is stabilized by two intra-molecular C-H⋯Cl contacts and one intra-molecular C-H⋯O contact, forming S(5)S(5)S(6) ring motifs. In the crystal, the mol-ecules are linked along the a-axis direction through van der Waals forces and along the b axis by face-to-face π-stacking between the thio-phene rings and between the benzene rings of neighbouring mol-ecules, forming corrugated sheets lying parallel to the bc plane. The inter-molecular inter-actions in the crystal packing were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are Cl⋯H/ H⋯Cl (28.6%), followed by C⋯H/H⋯C (11.9%), C⋯C (11.1%), H⋯H (11.0%), Cl⋯Cl (8.1%), O⋯H/H⋯O (8.0%) and S⋯H/H⋯S (6.6%).

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...

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
