Tetrakis(3,4-ethylenedioxy-2-thienyl)silane carbon tetrachloride solvate.

The structure of tetrakis(3,4-ethylenedioxy-2-thienyl)silane carbon tetrachloride solvate, Si(C(6)H(5)O(2)S)(4).CCl(4), has been determined in the noncentrosymmetric space group I-4. The Si and C atoms of the CCl(4) are located on the fourfold inversion axes. The Si atom has a tetrahedral geometry. The thiophene ring in the 3, 4-ethylenedioxythiophene group is nearly planar to within 0.005 A, and the ethylenedioxy moiety is in a half-chair conformation.
