Аннотация

3-chloro-N-(8′-quinolyl)benzo[b]thiophene-2-carboxamide was synthesized from 3-chlorobenzo[b] thiophene -2-carboxyl chloride and 8-aminoquinoline in the presence of triethylamine. The single crystal X-ray structure determination confirmed the earlier proposed structure and also characterized by 1HNMR, and Mass spectroscopy. Crystallographic study reveals that the structure crystallizes in monoclinic system, a = 14.878(4), b = 8.4292(15), c = 25.461(7) Å, β = 112.022(18)°, Z = 8, V = 2960.20(12) Å3 with space group C2/c (No. 15). In the structure packing, three kinds of interactions are responsible for the stability of the structure. Infinite two-dimensional stair-like layered chains are formed by relatively strong intermolecular hydrogen bonds [C14-H14…O1]. These parallel chains are connected by several
π-π and CH-π interactions, alternatively. There are two such parallel chains with 70.53°, which are in contact by van der Waals interactions.
