Dicarbonyl(cyclopentadienyl)manganese Clusters Containing SbCl-and SbCl2-Bridging LigandsSbCl3 undergoes partial dehalogenation when treated with C5H5(CO)2MnTHF in THF. Depending upon the reaction conditions [(C5H5(CO)2Mn)2SbCl]Mn(CO)2C5H5 (2), the first compound to contain a cyclic dimetallastibane ligand, or the open-chain complex C5H5 (CO)2 -Mn—SbCl2—C5H5(CO)2Mn—SbCl2—Mn(CO)2C5H5 (3) are formed. 3 contains a trans-dicarbonyl(cyclopentadienyl)bis(dichlorostibino)manganese ligand C5H5(CO)2(SbCl2)2Mn, not known in the free state. Each of the two Sb atoms of this ligand is bonded to a C5H5(CO)2 Mn moiety within the complex 3. Syntheses, properties as well as X-ray structure analyses of 2 and 3 are described.
Notes:
SbCl3 läßt sich mit C5H5(CO)2MnTHF in THF partiell enthalogenieren. Je nach den Reaktionsbedingungen entsteht [(C5H5 (CO)2Mn)2 SbCl]Mn(CO)2C5H5 (2), die erste Verbindung mit einem cyclischen Dimetallastiban-Liganden, oder der offenkettige Komplex C5H5(CO)2 -Mn-SbCl2—C5H5(CO)2 Mn—SbCl2—Mn(CO)2C5H5 (3). In 3 sind beide Antimonatome des im freien Zustand unbekannten trans-Dicarbonyl(cyclopentadienyl)bis(dichlorstibino)mangan-Liganden, C5H5(CO)2(SbCl2)2Mn, an je eine C5H5(CO)2 Mn-Einheit gebunden. Synthese, Eigenschaften und Röntgenstrukturanalyse von 2 und 3 werden beschrieben.
