Abstract
Chiral crystals of organic compounds have many potential applications, particularly in laser technology. The first case among oligothiophene s of chirality in the solid state is reported, the crystal structure b eing given along with selected NMR data and force field MM2 calculatio ns that provide information about the conformational properties of the compound in solution. Two structural features new for alpha-conjugate d oligothiophenes are exhibited: a chiral space group and a crystal pa cking that involves short van der Waals contacts.
