(DT-TTF)2[Pd(mnt)2]: An unusual ionic salt

The charge transfer salt based on the organic donor dithiophene‐tetrathiafulvalene and palladium bis‐maleonitrile‐dithiolate, (DT‐TTF)2[Pd(mnt)2], was obtained as single crystal by electrocrystallisation in dichloromethane. The crystal structure is different from the analogues previously described with other metals (Au, Cu, Ni and Pt) but of the same type as (TTDM–TTF)2[Au(mnt)2]. However in this DT‐TTF salt the Pd complex is dianionic, being the donor molecules fully oxidised and the compound should then be formulated as (DT‐TTF+)2[Pd(mnt)2]2–. This compound has properties of a quasi‐one‐dimensional semiconductor with sRT∼ 6 × 10–2 Scm–1 and Ea∼0.172 eV (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
