We report the synthesis, magnetic properties, and transport properties of paramagnetic metal complexes, [Co(DMF)(4)(TCNQ)(2)](TCNQ)(2) (1), [La(DMF)(8)(TCNQ)](TCNQ)(5) (2), and [Nd(DMF)(7)(TCNQ)](TCNQ)(5) (3) (DMF = N,N-dimethylformamide, TCNQ = 7,7,8,8-tetracyanoquinodimethane). All three compounds contain fractionally charged TCNQ(delta-) anions (0 < delta < 1) and mononuclear complex cations in which the coordination environment of a metal center includes several DMF molecules and one or two terminally coordinated TCNQ(delta-) anions. The coordinated TCNQ(delta-) anions participate in pi-pi stacking interactions with noncoordinated TCNQ(delta-) anions, forming columnar substructures that provide efficient charge-transporting pathways. As a result, temperature-dependent conductivity measurements demonstrate that all three compounds exhibit semiconducting behavior.
