Abstract
The cyclohexane ring of the title compound, C17H14N4-OS, shows disorde r with an 85% major conformer and a 15% minor conformer. Both adopt ha lf-chair conformations. The phenyl ring is tilted by 80.79(4)degrees t o the plane formed by the rest of the atoms of the molecule. Molecules of the same orientation are linked by C-H ... O hydrogen bonds and sh ort S ... O contacts, forming chains along the b axis.
