The Structure and Magnetic and Electrical Conductivity Properties of the Charge Transfer Compound 1,1′-Dimethylferrocenium Bis-(Tetracyanoquinodimethane), [(CH3C5H4)2Fe][TCNQ]2
Metallocenes react with tetracyanoquinodimethane (TCNQ) to yield charge transfer compounds predominantly of the stoichiometry [metallocene][TCNQ] or [metallocene][TCNQ]2.1,2 The 1:2. compounds have relatively high electrical conductivities which range from 4 ohm-1cm-1 for [(C5H5)2Fe][TCNQ]2 to 0.03 ohm-1cm-1 for [(CH3C5H4)2Fe]-[TCNQ]2,1 but, up to now, difficulties in obtaining high quality single crystals have prevented structural determinations.
