Abstract

The X-ray structure analysis of 2,2'-spirobi(1,3-benzodithiole), C(13)H(8)S(4), has been performed. The molecule has crystallographic twofold rotation symmetry, the axis passing through the spiro-C atom. The four S atoms are arranged around the spiro-C atom in two almost orthogonal CS(2) planes. However, because of large bending of the two five-membered rings, close contact is present between two connected C atoms on the benzo group of each 1,3-benzodithiole ring and one S atom on the other 1,3-benzodithiole ring.
