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

The title compound, [Rh(C8H12)(C18H36P2)]BF4, exhibits a rhodium(I) complex cation with a bidentate bisphosphine ligand and a bidentate η2,η2-coordinated cycloocta-1,5-diene ligand. The ligands form a slightly distorted square-planar coordination environment for the Rh(I) atom. An intramolecular P–Rh–P bite angle of 83.91 (2)° is observed. The dihedral angle between the P—Rh—P and the X—Rh—X planes (X is the centroid of a double bond) is 14.0 (1)°. The BF4 anion is disordered over two positions in a 0.515 (7):0.485 (7) ratio.
