A cobalt(II) compound, [Co-II(terpy)(2)](TCNQ)(4)center dot 3DMF center dot 0.5H(2)O (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 center dot(delta-) (0<1) radical anions. Single-crystal structures characterized at different temperatures demonstrated non-integer charge distribution among TCNQ radicals. Moreover, electric conductivity measurements revealed that I act as semiconductor at 300 K (3.3 x 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.
