Abstract
A single crystal X-ray structure analysis of [ttf][Rh(CO)2Cl2] revealed the segregated columnar stackings both of tetrathiafulvalene radical cations, ttf˙+, and of [Rh(CO)2Cl2]– anions with eclipsed overlaps. The crystals are orthorhombic, space group Pbam, with unit-cell dimensions a= 14.596(3), b= 12.487(3), c= 3.584(1)Å, and Z= 2. Least-squares refinement, based on 804 independent reflections with |Fo| > 3σ(F) converged at R= 0.070. The salt exhibits an electrical conductivity of 2.1 × 10–4 S cm–1 at 25 °C for a compacted pellet. Electronic states are discussed based on i.r., electronic powder reflectance, and e.s.r. spectra.Keywords
