{The structure of the iodo-substituted tetrathiafulvalene derivative EDT-TTF-I is described, with neutral molecules associated into inversion-centred dyads; no short intermolecular I...I contacts are observed. Electrocrystallisation of EDT-TTF-I (1) or EDT-TTF-I-2 (2) in the presence of {[}nBu(4)N]{[}Ni(mnt)(2)] afforded 2:1 salts, formulated as {[}1](2){[}Ni(mnt)(2)] and {[}2](2){[}Ni(mnt)(2)]. In both salts the organic donor molecules 1 or 2 are associated into inversion-centred dyads, connected to the {[}Ni(mnt)(2)] species through a short, directional CN...I interaction. The dyads alternate with the nickel dithiolene complex into mixed... DDADDADDA... stacks. Comparisons in both salts of intramolecular bond lengths, intra-dyad overlap modes, and magnetic susceptibilities, indicate a full charge-transfer in {[}1](2){[}Ni(Mnt)(2)], formulated as {[}1](2)(2+), {[}Ni(mnt)(2)](2-), while a mixed-valence state is observed in 2 {[}2](2)(+.){[}Ni(mnt)(2)](-.).
