Abstract
in N-butylthiophen-3-carboxamide, C9H13NOS, the N-butylcarboxamide gro up is almost planar with the aromatic thiophene ring, with the amide N atom cis to C2. In the 2-benzylseleno derivative, C16H19NOSSe, the N- butylcarboxamide group adopts an orientation with the amide O atom cis to C2 and forming a close contact with the Se atom. In both compounds , the amide N atom is involved in hydrogen bonding with the O atom of an adjacent molecule forming zigzag chains.
