Bis{(E)-N′-[2,4-bis(trifluoro­meth­yl)benzyl­idene]isonicotinohydrazide} monohydrate

The asymmetric unit of the title compound, 2C(15)H(9)F(6)N(3)O·H(2)O, 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 rin...

description The asymmetric unit of the title compound, 2C(15)H(9)F(6)N(3)O·H(2)O, 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.
