摘要: Decamethylchromocen, (C5(CH3)5)2 Cr, bildet mit CO den 18-Elektronen-Komplex (C5(CH3)5)2Cr(CO). Unter hoheren CO-Drucken entsteht der Dicarbonyl-Komplex (C5(CH3)5)2Cr(CO)2, auch in Abwesenheit von stabil ist. Eine Rontgenstrukturanalyse ergibt, das diese Verbindung einen η3- und η5-koordinierten Ringliganden enthalt damit ebenfalls als 18-Elektronen-Teilchen vorliegt. Mono- and Dicarbonyl Complexes of Decamethylchromocene Decamethylchromocene, (C5(CH3)5)2Cr, reacts with at ambient pressure to form the 18-electron species At elevated pressures, dicarbonyl complex (C5(CH3)5)2Cr(CO)2 is formed, which persists absence CO. An X-ray structure determination shows presence one η5-coordinated ring ligand hence an configuration even for this compound.
