Abstract

Four charge-transfer complexes of C3h-BTT (2) with the organic acceptors TCNQ, F4TCNQ, chloranil, and fluoranil were prepared and crystallographically characterized. All four complexes form mixed stacks of donors and acceptors in a 1:1 or 2:1 stoichiometry. The degree of charge transfer in these complexes was estimated based on bond distances, infrared spectroscopy, and magnetic properties. Of the four complexes, C3h-BTT·F4TCNQ exhibited the highest ionicity with ρ = 0.27e. All four complexes were diamagnetic.
