Thieno[2,3-c]pyridine, the First Structure of a Thienopyridine

The title molecule, C₇H₅NS, is planar to within 0.009 Å. Bond lengths at the hetero atoms are S1—C2 1.7276 (14), S1—C7a 1.7308 (13), N6—C5 1.354 and N6—C7 1.332 (2) Å; the C—S—C angle is 90.76 (6)°. A libration analysis indicated corrections of 0.003–0.004 Å. Short intermolecular contacts S1...N6 3.229 (1) Å link the molecules into chains parallel to the y axis.
