Abstract
(TTM-TTF)(CuI)2. {TTM-TTF = Tetra(methylthio)-tetrathiafulvalene}. the product of the reaction of TTM-TTF with CuI in an I2, atmosphere, is monoclinic C2/m, a = 7.928(2). b = 13.272(1), c = 10.523(2) Å, β 107.82(2)° V = 1054 Å3 Z = 2, dc = 2.42 g cm-3,μ = 56.8 cm-1, final Rw = 0.027 for 964 reflections and 59 variables. The donor acts as a bridging chelate ligand by coordination of the SCH3-groups to Cu. (TTM-TTF)+(CuCl2]- is triclinic P1̄, a = 7.253(1), b = 7.657(1), c = 10.256(1) Å, α = 89.63(1), β = 89.98(1), 3̄̄μ1̄γ = 73.26(1)°, V = 470 Å3 Z = 1, dc = 2.07 g cm-1, μ = 22.95 cm-1, final Rw = 0.029 for 1871 reflections and 104 variables. Stacks of the (TTM-TTF)+ radical cations with intrastack S···S-contacts of 3.792(2) Å. (TTM-TTF)2+[AuCl4]2 - and C4H6S4AuCl2 were obtained as products of the reaction of TTM-TTF with AuCl3 in acetonitrile. (TTM-TTF)2+[AuCl4]2 - is monoclinic, C2, a = 14.799(2), b = 11.513(2), c = 8.034(3) Å, β = 97.05(3)°, V = 1359 Å3, Z = 2, dc = 2.61 g cm-3, μ = 121.6 cm-1, final Rw = 0.028 for 1581 reflections and 140 variables. Stacks of the oxidized donor with intrastack S···S-contacts of 3.683(6) Å. C4H6S4AuCl2 is monoclinic. P21/n, a = 10.722(2), b = 14.054(3), c = 14.877(2) Å, β = 108.03(2)°, V = 2132 Å3, Z = 8, dc = 2.80 g cm-3, μ = 149.8 cm-1, final Rw = 0.029 for 3053 reflections and 212 variables. The molecules are arranged in stacks which shortest S···S-contacts of 3.269(3) Å
