Description
Summary:In the title compound, C(18)H(11)ClN(4)OS, the benzisoxazole and imidazothia-diazole rings are inclined at an angle of 23.81 (7)° with respect to each other. The imidazothia-diazole and chloro-phenyl rings make a dihedral angle of 27.34 (3)°. In the crystal, inter-molecular C-H⋯N inter-actions generate a chain along the c axis and C-H⋯O inter-actions form centrosymmetric dimers resulting in an R(2) (2)(26) graph-set motif. Moreover, the C-H⋯N and S⋯N [3.206 (4) Å] inter-actions links the mol-ecules into R(7) ring motifs. The packing is further stabilized by π-π stacking inter-actions between the thia-diazole rings with a shortest centroid-centroid distance of 3.497 (3) Å. In addition, C-H⋯π inter-actions are observed in the crystal structure.
