4-[(3-Oxo-1,3-dihydro-2-benzofuran-1-yl)amino]benzoic acid
In the title compound, C15H11NO4, the dihedral angle formed by the benzene ring and the essentially planar 2-benzofuran ring system is 55.93 (3)°. In the crystal, intermolecular O—H⋯O hydrogen bonds link pairs of molecules, generating centrosymmetric R
2
2(8) ring motifs. These dimeric units are connected via N—H⋯O hydrogen bonds, forming C(6) chains along [100]
4-(2-Sulfanylidene-1,3-benzothiazol-3-yl)butan-2-one
In the title compound, C11H11NOS2, the benzine ring is coplanar with the thiazole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent molecules are connected into a helical chain along the b axis by S⋯S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by intermolecular C—H⋯O hydrogen bond between aromatic ring H atoms and carbonyl groups
