    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)-N-... hydrogen bond. In (E)-3-phenyl-2-(3-thienyl)acrylonitrile, C13H9NS, the molecules are linked into sheets by a combination of one C-(HN)-N-... hydrogen bond and one C-H H-...pi(arene) hydrogen bond.
