(+)-{1,2-Bis[(2R,5R)-2,5-dimethylphospholan-1-yl]ethane-κ2P,P′}(η4-cycloocta-1,5-diene)rhodium(I) tetrafluoridoborate

Abstract

The title compound, [Rh(C8H12)(C14H28P2)]BF4, exhibits a rhodium(I) complex cation with a bidentate bisphosphine ligand and a bidentate η2,η2-coordinated cycloocta-1,5-diene. Together the ligands create a slightly distorted square-planar cordination environment for the Rh(I) atom. There are three molecules in the asymmetric unit and intramolecular P—Rh—P bite angles of 82.78 (5), 82.97 (6) and 83.09 (5)° are observed. The dihedral angles between the P—Rh—P and the X—Rh—X planes (X is the centroid of a double bond) are 14.7 (1), 14.8 (1) and 15.3 (1)°. The structure exhibits disorder of one cyclooctadiene ligand as well as one BF4 anion.
