title: 3-(2-Amino-1,3-thia-zol-4-yl)-6-chloro-2H-chromen-2-one.
abstract: The title compound, C(12)H(7)ClN(2)O(2)S, crystallizes with two mol-ecules in the asymmetric unit. The mol-ecular conformation is roughly planar for both these mol-ecules with maximum deviations of 0.177 (3) and 0.076 (4) Å from their respective mean planes. In the crystal, strong N-H⋯N and weak but highly directional C-H⋯O hydrogen bonds provide the links between the mol-ecules. The structure is further stabilised by aromatic π-π stacking inter-actions with centroid-centroid distances in the range 3.650 (3)-3.960 (3) Å.
