Abstract: Thirteen TCNQ charge transfer salts of tetraarylporphinatomanganese complex ions with the general formula [TAPMn] [TCNQ]_n (TAPH₂=tetraarylporphyrin; A=C₆H₅, 4-CH₃C₆H₄, 4-CH₃OC₆H₄, 4-ClC₆H₄, 3-ClC₆H₄, 3-FC₆H₄, 2,4-Cl₂C₆H₃, 4-Me₂NC₆H₄; TCNQ=7,7,8,8-tetracyanoquinodimethane; n=1, 2) have been synthesized and characterized by elementary analyses, IR spectra, X-ray photoelectron spectra, ESRspectra, magnetic susceptibilities and conductivities. The results indicate that there are TCNQ^- and TCNQ⁰ in the molecules of these charge-transfer salts as well as interaction between TCNQ^- and TCNQ⁰. It leads manganese of these compounds to mixed valence state because partial electrons transfer from [TCNQ]_n^- to [TAPMn]⁺. The room temperature conductivities of the complex salts are between 10^-7 and 10^-10S·cm^-1, they belong to organic semiconductor. The conductivities of the simple salts are lower than 10^-11 S·cm^-1 .
