The SO 2 coordination mode at the rhodium complex [ClRh(P∼O)()] ( 1 ) [ η 2 ( O,P )‐chelated Cy 2 PCH 2 CH 2 OCH 3 ligand; P∼O 1 ( P )‐coordinated] is controlled by the hemilabile ligand Cy 2 PCH 2 CH 2 OCH 3 and shows a dependence on the polarity of the solvent. In polar organic solvents (e.g. acetone) the addition of sulfur dioxide results in the formation of a trigonal‐pyramidal oriented SO 2 group in [ClRh(η 1 ‐SO 2 )(P∼O)()] ( 2a ). However, in nonpolar media (e.g. n ‐hexane) a trigonal‐coplanar geometry of the SO 2 unit in [ClRh(η 1 ‐SO 2 )(P∼O) 2 ] ( 2b ) is favored.
