STRUCTURE OF (ETA(5)-CYCLOPENTADIENYL)BIS-(DIMETHYLPHENYLPHOSPHINE)PALLADIUM(II) PERCHLORATE

In the crystal structure of [Pd(eta5-C5H5)(PMe2Ph)2]-ClO4 the asymmetric unit contains two cations and two anions, one cation adopting a nearly eclipsed, and the other a staggered orientation of the C5H5 ring with respect to the perpendicular Pd(PMe2Ph)2 fragment. The coordination geometry around the metal atom is distorted square planar in both rotamers. The Pd-P distances are 2.250 (2)-2.253 (2) angstrom and the Pd-C distances vary from 2.252 (8)-2.343 (6) angstrom.
