title: Synthesis and Oxidation of a Paddlewheel-Shaped Rhodium/Antimony Complex Featuring Pyridine-2-Thiolate Ligands.
abstract: The paddlewheel-shaped complex [Sb(μ-pyS)4Rh]2(1) (pyS-= 2-S-C5H4N-) was synthesized from [Rh(pyS)(cod)]2(cod=1,5-cyclooctadiene) and Sb(pyS)3. Upon oxidation with ONMe3, the complex [(μ-O)Sb(μ-pyS)3Rh(κ2-pyS)]2(2) is formed. Both 1 and 2 form dimers and feature short Rh-Sb bonds and bridging pyS ligands.121Sb Mössbauer spectro- scopy and computational studies were employed to elucidate the Rh-Sb bonding in 1 and 2. Both covalent (Rh-Sb, X-type Sb ligand) and dative (Rh→Sb, Z-type; Rh←Sb L-type Sb ligand) interactions have to be considered for the description of their bonding situations.
