摘要

A cobalt(II) compound, [Co^II(terpy)₂](TCNQ)₄·3DMF·0.5H₂O (1; terpy = 2,2′;6′,2″-terpyridine, TCNQ = 7,7′,8,8′-tetracyanoquinodimethane), was found to show incomplete spin-crossover properties in the cobalt(II) complex and semiconducting properties in the quasi one-dimensional packed TCNQ[rad]^δ − (0 < δ < 1) radical anions. Single-crystal structures characterized at different temperatures demonstrated non-integer charge distribution among TCNQ radicals. Moreover, electric conductivity measurements revealed that 1 act as semiconductor at 300 K (3.3 × 10^− 4 S cm^− 1). The coexistence of spin crossover and electric conductivity in one system will pave the way to study the interactions of such different properties and for the implementation of multifunctional materials.
