摘要：

The molecules of (2RS,4SR)-2-exo-(5-bromo-2-thienyl)-7-chloro-2,3,4,5-tetrahydro-1H-1,4-epoxy-1-benzazepine, C14H11BrClNOS, (I), are linked into cyclic centrosymmetric dimers by C-H center dot center dot center dot pi( thienyl) hydrogen bonds. Each such dimer makes rather short Br center dot center dot center dot Br contacts with two other dimers. In (2RS,4SR)-2-exo-(5-methyl-2-thienyl)-2,3,4,5-tetrahydro-1H-1,4-epoxy-1-benzazepine, C15H15NOS, (II), a combination of C-H center dot center dot center dot O and C-H center dot center dot center dot pi(thienyl) hydrogen bonds links the molecules into chains of rings. A more complex chain of rings is formed in (2RS,4SR)-7-chloro-2-exo-(5-methyl-2-thienyl)-2,3,4,5-tetrahydro-1H-1,4-epoxy-1-benzazepine, C15H14ClNOS, (III), built from a combination of two independent C-H center dot center dot center dot O hydrogen bonds, one C-H center dot center dot center dot pi(arene) hydrogen bond and one C-H center dot center dot center dot pi(thienyl) hydrogen bond.
