1,7-Diethyl-4,10-diisopropyltetracene

Abstract

The molecule of the title compound, C28H32, is located on a crystallographic inversion center. The ethyl groups are essentially coplanar with the tetracene 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 tetracene plane [the Me—C—C—C torsion angles are −22.5 (4) and 100.9 (3)°]. In the crystal, the molecules adopt an arrangement without significant π–π interactions along the stacking direction (y axis).
