The asymmetric unit of the title compound, C17H20N4S, contains two independent mol-ecules, the main difference between them being the dihedral angles between the benzene rings [19.99 (17) and 9.72 (17)°]. The mol-ecules both have a trans conformation about the C=N double bond and intra-molecular C-H⋯S and N-H⋯N hydrogen bonds are observed in both mol-ecules. In the crystal, mol-ecules are linked by weak N-H⋯S hydrogen bonds with graph-set motif R 2 (2)(8). In each mol-ecule, all but one of the N atoms and both the S atoms are involved in hydrogen bonding.
标题化合物C₁₇H₂₀N₄S的不对称单元包含两个独立分子，它们之间的主要区别在于苯环之间的二面角[19.99 (17) 和9.72 (17)°]。两个分子关于C=N双键均呈反式构象，且在两个分子中均观察到分子内C-H⋯S和N-H⋯N氢键。在晶体中，分子通过弱N-H⋯S氢键以R 2 (2)(8)的图形集模式相连。在每个分子中，除一个N原子外的所有N原子以及两个S原子均参与氢键形成。
