4-[(1-Benzyl-1H-1,2,3-triazol-4-yl)methoxy]benzene-1,2-dicarbonitrile: Crystal structure, Hirshfeld surface analysis and energy-minimization calculations

In the solid state, the title compound, C₁₈H₁₃N₅O, adopts a conformation whereby the phenyl ring and methoxy-benzene-1,2-dicarbonitrile residue (r.m.s. deviation of the 12 non-H atoms = 0.041 Å ) lie to opposite sides of the central triazolyl ring, forming dihedral angles of 79.30 (13) and 64.59 (10)°,respectively; the dihedral angle between the outer rings is 14.88 (9)º. This conformation is nearly 7 kcal mol^-1 higher in energy than the energy-minimized structure which has a syn disposition of the outer rings, enabling intramolecular π- π interactions. In the crystal, methylene-C-H···N(triazolyl) and carbonitrile- N···π(benzene) interactions lead to supramolecular chains along the a axis. Supramolecular layers in the ab plane arise as the chains are connected by benzene-C-H···N(carbonitrile) interactions; layers stack with no directional interactions between them. The specified intermolecular contacts along with other, weaker contributions to the supramolecular stabilization are analysed in a Hirshfeld surface analysis.
