title: (+)-{1,2-Bis[(2R,5R)-2,5-dimethyl-phospho-lan-1-yl]ethane-κP,P'}(η-cyclo-octa-1,5-diene)rhodium(I) tetra-fluorido-borate.
abstract: The title compound, [Rh(C(8)H(12))(C(14)H(28)P(2))]BF(4), exhibits a rhodium(I) complex cation with a bidentate bis-phosphine ligand and a bidentate η(2),η(2)-coordinated cyclo-octa-1,5-diene. Together the ligands create a slightly distorted square-planar cordination environment for the Rh(I) atom. There are three mol-ecules in the asymmetric unit and intra-molecular 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 cyclo-octa-diene ligand as well as one BF(4) anion.
