Özet

The asymmetric unit of the title compound, C25H18N6 center dot H2O, comproses two molecules (I and II), together with a water molecule. The terminal phenyl groups attached to the methyl groups of the molecules I and II do not overlap completely, but are approximately perpendicular. In the crystal, the molecules are connected by N-H center dot center dot center dot N, C-H center dot center dot center dot N, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds with each other directly and through water molecules, forming layers parallel to the (001) plane. C-H center dot center dot center dot pi. interactions between these layers ensure the cohesion of the crystal structure. A Hirshfeld surface analysis indicates that H center dot center dot center dot H (39.1% for molecule I; 40.0% for molecule II), C center dot center dot center dot H/H center dot center dot center dot C (26.6% for molecule I and 25.8% for molecule II) and N center dot center dot center dot H/H center dot center dot center dot N (24.3% for molecules I and II) interactions are the most important contributors to the crystal packing.
