In the title compound, C19H13BrN2O5, the spiro furan ring is almost planar with a maximum deviation of 0.034 (2) Å. The indole unit and the furan ring are normal to each other, making a dihedral angle of 87.82 (8) °. The molecular structure is stabilized by an intramolecular N—HO hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked via pairs of N—HO hydrogen bonds, forming inversion dimers enclosing R22(8) ring motifs.

In the title compound, C17H20ClN3OS, the mean plane of the central thiourea core makes dihedral angles of 26.56 (9) and 47.62 (12)° with the mean planes of the chromene moiety and the cyclohexyl ring, respectively. The cyclohexyl ring adopts a chair conformation. The N–H atoms of the thiourea unit adopt an anti conformation. The chromene group is positioned trans, whereas the cyclohexyl ring lies in the cis position to the thione S atom, with respect to the thiourea C—N bond. In the crystal, molecules are linked by N—HS hydrogen bonds, forming inversion dimers enclosing R22(8) ring motifs. The dimers are linked by C—HCl hydrogen bonds, enclosing R66(44) ring motifs, forming sheets lying parallel to (010).
