چکیده
The title compound, C7H11N3O2S, exists in the 5-thioxo tautomeric form. The 1,2,4-triazoline ring is essentially planar, with a maximum deviation of 0.010 (2) Å for the substituted N atom. The ethyl acetate substituent is almost planar, with a maximum deviation of 0.061 (4) Å for the methyl-ene C atom of the eth-oxy group. The angle between the mean plane of this substituent and the mean plane of the 1,2,4-triazoline ring is 89.74 (8)°. In the crystal, mol-ecules are linked by a combination of N-H⋯S, C-H⋯N and C-H⋯O hydrogen bonds into chains parallel to [100].

The title mol-ecule, C(26)H(35)N(5)O(2)S, displays a chair-shaped piperazine ring, as well as a planar triazole ring whose phenyl substituent is perpendicular to the mean plane of the five-membered ring [dihedral angle = 90.00 (13)°]. The methyl-ene substituent on the piperazine ring occupies an equatorial site. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. Th...
