| Popis: | The asymmetric unit of the title compound, 2C15H9F6N3O·H2O, contains two independent Schiff base molecules and one water molecule. Both Schiff base molecules exist in an E configuration with respect to the C=N double bonds and the dihedral angles between the benzene and the pyridine rings in the two molecules are 17.53 (12) and 20.62 (12)°. In the crystal structure, molecules are linked by intermolecular N—H...O and C—H...O hydrogen bonds into infinite one-dimensional chains along the a axis. In addition, intermolecular O—H...N, O—H...F, C—H...F and C—H...O hydrogen bonds further link these chains into a three-dimensional network. Weak π–π interactions with centroid–centroid distances in the range 3.6495 (17)–3.7092 (16) Å are also observed. |
