The synthesis and crystal structure of the salt (BPDT-TTF) 2[W6O19] is described. The compound crystallizes in the triclinic space group P - 1 with a = 10.927(2) Å, b = 11.904(2) Å, c = 12.660(2) Å, α = 101.261(5)°, β = 115.174(5)°, and γ = 114.434(5)°. The bond length of the central C=C bond in BPDT-TTF is 1.384(17) Å, in accord with an oxidation state of +1 for the BPDT-TTF radical-cations and the observed stoichiometry between BPDT-TTF and [W6O19]2- which is 2:1. © 2009 Springer Science+Business Media, LLC.
