Abstract: The structure of (E)-2-(2-thienyl)-3-(3,4,5-trimethoxyphenyl)acrylonitrile, C₁₆H₁₅NO₃S, contains no direction-specific intermolecular interactions. The molecules of (E)-3-(4-bromophenyl)-2-(2-thienyl)acrylonitrile, C₁₃H₈BrNS, exhibit orientational disorder of the thienyl fragment, and the molecules are linked into simple C(5) chains by a single C-HN hydrogen bond. In (E)-3-phenyl-2-(3-thienyl)acrylonitrile, C₁₃H₉NS, the molecules are linked into sheets by a combination of one C-HN hydrogen bond and one C-H [pi] (arene) hydrogen bond.

Formula: C₁₆H₁₅NO₃S, C₁₃H₈BrNS and C₁₃H₉NS
