    In the title compound, C14H10BrF3O 4, the coumarin ring system is almost plannar (r.m.s. deviation = 0.025 Å) and a short C-H⋯F contact occurs. The propanoate fragment is orientated almost perpendicular to the ring [dihedral angle = 71.80 (12)°]. In the crystal, molecules are linked by C-H⋯O hydrogen bonds, generating [100] chains.

    In the title compound, C15H15NO, the dihedral angle between the benzene rings is 2.25 (2)°. The C - C - C - O atoms of the propanol side chain are in a gauche conformation [torsion angle = -60.5 (2)°]. In the crystal, O - H⋯O hydrogen bonds link the molecules into C(2) chains propagating in [100]. The O-bonded H atom is disordered over two sites of equal occupancy.

    The mol-ecular structure of the title compound, C 14H 18Br 2N 2O 2, has one half-mol-ecule in the asymmetric unit. The mol-ecule has a crystallographic inversion centre in the middle of the benzene ring. The C - C - N - C torsion angle between the benzene ring and the bromo-amide group is 149.2 (7)°. The crystal is stabilized by a strong inter-molecular N - H⋯O bond and weak C - H⋯O inter-actions. These contacts give rise to a three-dimensional network.

    In the title compound C33H30S6, the three pendant methyl-ene benzodithio-ate groups lie to one side of the central benzene ring in a cis-cis-cis tripod arrangement. The dihedral angles between the central benzene ring and the three pendant rings are 72.54 (4), 89.68 (4) and 86.74 (4)°. In the crystal structure, one of the benzene rings is disordered over two orientations in a 0.559 (13):0.441 (13) ratio.

    In the title compound C14H14BrNO3, the coumarin ring system is almost planar (r.m.s. deviation = 0.008 Å) and an intra-molecular C - H⋯O inter-action generates an S(6) ring. In the crystal, mol-ecules are linked by N - H⋯O hydrogen bonds, with the C=O unit of the coumarin ring system acting as the acceptor group, generating [010] C(8) chains. The chain connectivity is reinforced by two C - H⋯O inter-actions.
