Abstract
A novel radical cation salt based on of the donor (4,5-ethylenedithio-4′,5′-vinylenedithio)tetrathiafulvalene (EVT) with the square planar anion Pt(CN) 4 2− has been synthesized: (EVT) 4·[Pt(CN) 4] ( 1). According to the X-ray analysis its crystal structure includes EVT cation layers alternating with anion layers along the a-axis of the unit cell. The radical cation layer is formed by EVT stacks with β-packing type, the donors in stacks are tetramerized. The EPR spectra of a plate-like crystal of (EVT) 4·[Pt(CN) 4] salt shows a very weak signal with typical parameters of TTF derivative. The room temperature conductivity of salt 1 is 8×10 −2 Ω −1 cm −1 and the temperature dependence of the conductivity exhibits semiconducting character.
