The electrically conducting Cu-TCNQ complexes Cu(dpa)2(TCNQ)2, Cu(dpa)2(TCNQ)2·H2O, and Cu(dpa)(TCNQ)2 (dpa = di-2-pyridylamine; TCNQ = 7,7,8,8-tetracyanoquinodimethan) have been obtained by reactions of [Cu(dpa)n]2+ and TCNQ-?. The single crystals of Cu(dpa)2(TCNQ)2 exhibited high electrical conductivity (ca. 50 Ω-1 cm-1 at 300 K) that displayed metal-like temperature dependence. Other materials obtained as powders showed a semiconductive property (0.56-4.5 Ω-1 cm-1 at 295 K) with a small activation energy in a range of 0.02-0.05 eV. These compounds were characterized by magnetic susceptibility, electron spin resonance, infrared, and thermoelectric power experiments. The results indicated that the formula of each compound is given by Cu+(dpa)n[(TCNQ)2]- and also that one-dimensional lattices consisting of TCNQ0.5- yield the high electric conduction in every compound. The copper(II) chelates act as an appropriate oxidant against TCNQ-? to form the highly conducting materials.
