Zusammenfassung
Reaction of [Rh2(μ-pz)2(CO)2(PPh 3)2] (1) (pz = pyrazolate) with HgCl2 gives [(Ph3P)(CO)ClRh(μ-HgCl)(μ-pz)2Rh(CO)-(PPh 3)] (2); the X-ray stucture of (2) shows the presence of two rhodium atoms in different oxidation states asymmetrically bridged by a mercury atom, so that a unique RhIII-Hg←RhI fragment is present.
