چکیده
In the title hydrate, C(16)H(15)BrO(2)SSe·H(2)O, the sulfinyl O atom lies on the opposite side of the mol-ecule to the Se and carbonyl O atoms. The benzene rings form a dihedral angle of 51.66 (17)° and are splayed with respect to each other. The observed conformation allows the water mol-ecules to bridge sulfinyl O atoms via O-H⋯O hydrogen bonds, generating a linear supra-molecular chain along the b axis; the chain is further stabilized by C-H⋯O contacts. The chains are held in place in the crystal structure by C⋯H⋯π and C-Br⋯π inter-actions.

The 1,4-dihydro-pyridine ring in the title hydrate, C(17)H(18)BrNO(2)·H(2)O, has a flattened-boat conformation, and the benzene ring is occupies a position orthogonal to this [dihedral angle: 82.19 (16)°]. In the crystal packing, supra-molecular arrays mediated by N-H⋯O(water) and O(water)-H⋯O(carbon-yl) hydrogen bonding are formed in the bc plane. A highly disordered solvent mol-ecule is prese...

In the title mol-ecule, C(15)H(10)BrNO(3)S(2), the dihedral angle between the benzothia-zole ring system and the benzene ring is 67.57 (12)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O inter-actions. In addition, there is an inter-molecular Br⋯C [3.379 (3) Å] contact which is shorter than the sum of the van der Waals radii of these atoms.
