چکیده
In the title mol-ecule, C15H20N4OS2, the acetamido fragment is nearly coplanar with the pyridyl ring [C-N-C-C torsion angle = -4.1 (2)°], while the cyclo-hexyl-sulfanyl portion protrudes from this plane [N-C-C-S torsion angle = -40.8 (6)°]. In the crystal, alternating pairwise N-H⋯O and N-H⋯N hydrogen bonds across inversion centres form chains along [101], which are associated into stepped layers via offset π-π stacking between pyridyl rings [centroid-centroid distance = 3.566 (1) Å]. The cyclo-hexyl group and the two atoms of the S-C bond attached to it are disordered over two sets of sites with site-occupancy factors of 0.8845 (18) and 0.1155 (18).
