Crystal structure and Hirshfeld surface analysis of (2Z)-N,N-dimethyl-2-(pentafluorophenyl)-2-(2-phenylhydrazin-1-ylidene)acetamide

Abstract

In the title compound, C16H12F5N3O, the dihedral angle between the aromatic rings is 31.84 (8)°. In the crystal, the molecules are linked into dimers possessing crystallographic twofold symmetry by pairwise N—H...O hydrogen bonds and weak C—H...O hydrogen bonds and aromatic π–π stacking interactions link the dimers into a three-dimensional network. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from F...H/H...F (41.1%), H...H (21.8%), C...H/H...C (9.7%) C...C (7.1%) and O...H/H...O (7.1%) contacts. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported molecular weight and density.
