Abstract
The mol-ecule of the title compound, C(28)H(32), is located on a crystallographic inversion center. The ethyl groups are essentially coplanar with the tetra-cene ring, making a torsion angle of -0.4 (4)°. The isopropyl groups adopt an asymmetric conformation with their terminal methyl groups positioned on opposite sides of the tetra-cene plane [the Me-C-C-C torsion angles are -22.5 (4) and 100.9 (3)°]. In the crystal, the mol-ecules adopt an arrangement without significant π-π inter-actions along the stacking direction (y axis).
