Electrocrystallised metal–tetracyanoquinodimethane salts with high electrical conductivity
Abstract
Conductivities/Ω–1 cm–1 from ca. 10–5 to 800 [for Cu(TCNQ)] are obtained for salts, often novel, of the formulation M(TCNQ)n or M(TCNQ)n(solvent)m, prepared by cathodic electrocrystallisation from tetracyanoquinodimethane (TCNQ) in the presence of metal (M) salts, where the M are K, Mn, Fe, Co, Ni, Cu, Zn, Ag, and Cr.
