Synthese und Struktur von Dicarbonyl(η5-pentaphenylcyclopentadienyl)rhodium, (η5-C5Ph5)Rh(CO)2

Abstract
5-C5Ph5)Rh(CO)2 has been prepared in 62% yield by treatment of [Rh(CO)2Cl]2 with NaC5Ph5 in THF. The title com pound crystallizes in the rhombic space group Pcab with the lattice parameters a = 2064.7(7) pm , b = 2065.2(8) pm, c = 1407.6(6) pm and Z = 8 . The crystal structure consists of discrete (η5-C5Ph5)Rh(CO)2 molecules and the Rh(CO)2 fragment adopts an eclipsed conformation relative to the cyclopentadienyl ring.
