Abstract

Abstract: The title compound was synthesized by refluxing RuCl₃with cyclopentadiene in methanol. It crystallizes in space group C₅-P_nwith cell dimensions: a=0. 9735(4) nm, b=0. 8604(3) nm, c=1. 2261(6) nm, β=94. 83(3), and Z=2. Structure was solved by Patterson method and Fourier functions, and was refined to final Rvalue of 0. 0365 based on 1872 observable reflections. In contrast to the staggered conformation of decamethylferrocene, this molecule adopts the eclipsed comformation. The conformation difference was explained by the polarizability and metal atom size.

Key words: Synthesis, Structure, Cyclopentadienylruthenium
