Article

The charge transfer salts (DT-TTF)2[Ni(dcdmp)2], (DT-TTF)3[Cu(dcdmp)2]2 and (DT-TTF)3[Au(dcdmp)2]2, (dcdmp=2,3-dicyano5,6-dimercaptopyrazine) were obtained by electrocrystallisation and characterized. The Ni compound presents a structure consisting of stacks of fully oxidized donor pairs alternating with dianionic complexes. In the two other compounds the complex is monoanionic, the Au salt presenting a structure with stacks of donors triads alternating with pairs of complexes. All compounds display a semiconductor behavior with the highest electrical conductivity of 6.8 S/cm at room temperature being observed for the Cu salt.
