Abstract
The (EDOEDT)4Hg3Br8 radical cation salt of 4,5-ethylenedioxy-4′,5′-ethylendithiotetrathiafulvalene has been synthesized as a mixture of two crystalline phases. Phase 1 is characterized by a semiconducting type of conductivity and the ESR peak-to-peak linewidth equal to 70–95 G. Phase 2 exhibits metal-like conductivity down to 105 K and the ESR peak-to-peak linewidth of 35–54 G. The X-ray crystal structure analysis of phase 1 reveals three crystallographically distinct donor molecule layers in the asymmetric part of the unit cell, one of them being composed of the stacks and the two others are built of mutually perpendicular tetramers. The polarized reflectance spectra of phase 1 are discussed.
