Abstract
The reaction of CdI2 with an acetone solution of (Et(3)S)I (molar rati o 1:2) gives the title compound. The structure of [(C2H5)(3)S](2)[CdI4 ] contains discrete pyramidal Et(3)S(+) and tetrahedral CdI42- ions. T he bond distances of the two independent anions, Cd1-I1 and Cd2-I2, ar e 2.772(1) and 2.784(1) Angstrom, respectively. The cation, with appro ximate threefold symmetry, is disordered such that each of the middle methylene groups takes two positions with a ratio of ca 2:1.
