Abstract
Abstract The structure of chlorobis(tricyclohexylphosphine) (sulfur dioxide)rhodium(I) has been determined by single crystal X-ray techniques. The complex crystallizes in the space group P2 1 /c with cell constants of a = 13.371(6), b = 12.783(6), c = 23.293(10) A and β = 105.01(2)°. Refinements using 2822 unique reflections for which I⩾ 2 σ(I) included anisotropic temperature parameters for all atoms heavier than carbon and hydrogen atoms fixed in idealized positions converged to an unweighted R value of 6.6%. The coordination about the Rh atom is square planar with trans phosphines and a η 1 -planar SO 2 group. The conformation about the Rh S bond is determined by O---H interactions. The bonding of SO 2 to the complex is discussed.
