Abstract
Two electron-donating odd-numbered radialenes, tris(thioxanthen-9-ylidene)cyclopropane and pentakis(1,3-benzodithiol-2-ylidene)cyclopentane, were synthesized as a donor component for the preparation of purely molecular/organic ferromagnets, since their dications can be a ground state triplet, assuming that the molecular symmetries are C3 and C5, or their highers, respectively. The magnetic properties of the dication and charge-transfer complex salts obtained from the new donors are discussed -on the basis of results of ESR spectra and magnetic susceptibility.Keywords
