1(2,3),2(3,2),3(2,3),4(3,2)-Tetrakis(1-benzothiophena)cyclotetraphane benzene sesquisolvate

Abstract

In the title compound, C32H16S4·1.5C6H6, the substituted cyclooctatetraene (COT) ring compound has approximate local D2 point symmetry of the so-called `saddle' form: the dihedral angles between neighboring benzo[b]thiophene units are 61.33 (4), 61.61 (4), 56.443 (14) and 58.32 (4)°. The short distance [3.545 (1) Å] between an S atom and the centroid of a benzene ring in a neighboring molecule may indicate S...π interactions in the crystal.
