## Abstract

This study reports the crystal structure of a diimine compound incorporating 1,2-diphenylethane-1,2-diimine and diisobutyl substituents. The dihedral angle between the two phenyl rings in the asymmetric unit measures 89.23°. Molecular packing shows elongation along the a-axis and stacking along the b-axis. No intramolecular or intermolecular hydrogen bonds, nor aromatic π-π stacking interactions, were detected. Weak C-H⋯π(ring) contacts are proposed to contribute to the stabilization of the crystal lattice.

## Delivery context

The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
