Abstract
The substituted sandwich complex crystallizes in monoclinic space groupP21/m withZ=2. Twinning to the (001) direction with the special conditionc */4a * = cosβ * causes systematic superposition of the reciprocal lattices of both domains and results in an apparent unit cell with double volume and the reflection condition (2h)kl, l=2n. The structure solution was obtained with the subset of intensity data for the predominant individuum and converged atR = 0.040,R w =0.046 for 832 independent observations and 122 variables. The molecules show disorder with respect to the crystallographic mirror plane. The structure is closely related to that of decamethylruthenocene.
