Article abstract of DOI:10.1107/S0108270197002084

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