Bis[(E)-2-(2,4-dichloro-5-nitrostyryl)-1,3-benzothiazole] hydrate

The title compound, bis[(E)-2-(2,4-dichloro-5-nitrostyryl)-1,3-benzothiazole] hydrate, 2C15H8Cl2N2O2S.-H2O, was obtained from the condensation of 2-methyl-benzothiazole with 2,4-dichloro-5-nitrobenzaldehyde. Single-crystal X-ray analysis showed that the asymmetric unit contains two crystallographically unique but structurally similar molecules. The dihedral angle between the benzothiazole fragment and the phenyl ring is 6.1 (4) degrees in molecule A and 19.5 (4) degrees in molecule B.
