چکیده
In the title compound, C(16)H(13)N(5)O(2)S, the five non-H atoms of the urea linkage adopt a planar configuration owing to the presence of an intra-molecular N-H⋯O hydrogen bond. The maximum deviation from planarity is 0.022 (2) Å. The thia-diazole and pyridine heterocyclic rings are close to being coplanar, with a dihedral angle of 6.7 (2)° between their mean planes. Inter-molecular N-H⋯O hydrogen bonds link two neighbouring mol-ecules into centrosymmetric R(2) (2)(8) dimers. Four C atoms and the attached H atoms of the benzene ring are disordered over two positions of equal occupancy.
