| Abstract: | The structure of 4-methyl-6-phenyl-2-(thiobenzoylmethylene)-2H-thiapyran (1) was investigated by ESCA, X-ray analysis and quantum chemical calculations. The no-bond interaction between the sulphur atoms (Rs…s = 3.000(1) Å) is caused by π-type interaction rather than by Coulomb-type interaction. |
