Seven TCNQ charge-transfer salts of amine copper or nickel complex cations, [ML2] [TCNQ]n (TCNQ=7, 7, 8, 8-tetracyanoquinodimethane; n=2, 3; M=Cu, Ni; L=tn, pn, dien, dmtade), have been synthesized. These charge-transfer salts have been characterized by elemental analysis, infrared spectrum, electronic spectrum, electron paramagnetic resonance spectrum, XPS, susceptibility and conductivity. The results indicate that there are TCNQ^0 and TCNQ^- in the molecules of these charge-transfer salts as well as interaction between TCNQ^0 and TCNQ^-. The [TCNQ]n^2^- to [ML2]^2^+. Room temperature conductivities of the seven samples are in 10^-^5～10^-^1^0S.cm^-^1, therefore they belong to organic semiconductor. Their conductivities are mainly attributed to the formation of TCNQ molecular column of one dimension.
