In the crystal, centrosymmetric molecules are linked by pairs of C—H interactions into dimeric units, which are further connected by O–H N hydrogen bonds to form layers

The crystal packing features N—H O, O— H N and O—H O hydrogen-bond interactions, which lead to the formation of a chain along the c- axis direction through one of the

Three-molecule aggregates are formed via O—H N(pyridyl) hydrogen bonds, and these are connected into supramolecular layers in the bc plane by N—H O(carbonyl) hydrogen bonds and

Supramolecular arrays in the bc plane in (I) mediated by C–H··· π interactions shown as purple dashed lines.. supporting

These dimers are connected into two zigzag chains extending along the b axis through C—H··· π and another C—H···O interaction (Bernstein et al. The reaction mixture was

The absence of disorder in the thiophene ring facilitates one of its ring C atoms to participate in the lone intermolecular C—H  O hydrogen bond present in the crystal, leading to
