Synthesis, Structure, and Physical Properties of a New Organic Conductor Based on a π‐Extended Donor Containing a Stable 2,2,5,5‐tetramethyl‐1‐pyrrolidinyloxy Radical
Source abstract
Abstract
A stable-organic-radical-functionalized tetrathiapentalene organic conductor has been synthesized and studied using X-ray crystallography of very small single crystals. The crystal structure reveals alternating conducting and insulating layers (see Figure).

Data collection was performed on a Rigaku AFC‐8 Mercury CCD diffractometer with confocal X‐ray mirror system (Mo Kα radiation: λ = 0.7107 Å) and a rotating anode generator (0.8 kW). Intensities were collected to a maximum 2θ value of 54.3° by the ω scanning technique. 10 975 independent reflections were measured of which 3411 were considered to be observed [I > 3.00 σ(I)]. The structure was solved by a direct method (SIR92). The non‐hydrogen atoms were refined anisotropically. Hydrogen atoms were included but not refined. The structure was refined by full‐matrix least squares toR = 0.094 Rw = 0.068 andGOF = 1.11. All calculations were performed using the CRYSTALS crystallographic software package. CRYSTALS: D. J.
