N‐(3‐benzoyl‐4,5,6,7‐tetrahydrobenzo[b]thiophen‐2‐yl)‐2,6‐difluorobenzamide, C22H17F2NO2S, (III), and N‐(3‐benzoyl‐4,5,6,7‐tetrahydrobenzo[b]thiophen‐2‐yl)‐2‐methoxybenzamide, C23H21NO3S, (IV), the last of which crystallizes with Z′ = 2 in the space group P, the fused six‐membered ring adopts a half‐chair conformation. In each of (I)–(III), this ring is disordered over two sets of atomic sites having occupancies
