Structure of 2-(2'-thienyl)pyridine at 193 K

The molecular geometry of the thiophene and pyridine rings is very similar to other derivatives. Both rings are planar and almost in the same plane. The slight twist between the two planes arises froom the intramolecular short contact between S and N. The C4'-C5'bond between the thiophene and pyridine rings is a partial double bond as a result of conjugation
