Abstract
Tetrakis(hydroxyacetato)bis(dimethyl sulfoxide)dirhodium(II) (1) is synthesized by the reaction of dimethyl sulfoxide (DMSO) with Rh2(OOCCH2OH)4. The complex is characterized by elemental analysis, FT-IR, ESI+-MS, 1H and 13C NMR, along with single crystal X-ray diffraction. The ambidentate DMSO ligands are bound to the rhodium center of 1 through their sulfur atoms, which is firstly predicated by its orange color, then confirmed by the observation of an increase in the S–O stretching frequencies, and finally, unambiguously determined by single crystal X-ray diffraction. The structure of 1 contains two similar but crystallographically independent molecules. Both molecules contain lantern dirhodium units, joined equatorially by four bidentate hydroxyacetate ligands and two monodentate DMSO axial ligands. Four hydrogen bonds link the molecules together with d(O⋯O) of 2.767(4)-2.824(4) Å to form a three dimensional network.
