Abstract The new radical-cation salt (BEDT-TTF)4Cd2I6 has been studied by x-ray diffraction (a=19.284(6), b=12.84(1), c=7.869 (2) Å; α=72.77(4), β=94.44(2), γ= 103.97(3)o, space group P1, Z=1, dcalc=2.32 g/cm3). The radical cation (BEDT-TTF)1/2+ and the Cd2I6 2− anions form organic and inorganic layers alternating along the a axis. In the organic layer, (BEDT-TTF)1/2+ are arranged in stacks and ribbons. The radical-cations in the ribbon are packed “side to side” and are joined to one another through shortened intermolecular contacts S...S 3.346(5)-3.657(4) Å. The Cd2I6 2− anion is dimeric. The Cd atom has a distorted tetrahedral bond configuration, with bond lengths Cd-I 2.722(l)-2.886(1) Å and valence angles I-Cd-I 93.8(1)-114.1(1)∘.
