Bis(pentamethylcyclopentadienyl)germanium und ‐zinn sowie (Pentamethylcyclopentadienyl)germanium‐ und ‐zinn‐Kationen: Synthese, Struktur und Bindungsverhältnisse

Abstract: Synthese und Eigenschaften des Bis(pentarnethylcyclopentadieny1)germaniums (2) und -zinns (1) sowie der ionischen (Pentamethy1cyclopentadienyl)gerrnanium-und -zinn-tetrafluoroborate 4 und 3 werden beschrieben. Die Strukturen von 1 -4 resultieren aus spektroskopischen und analytischen Daten sowie im Falle von 1 und 3 auch aus Rontgenstrukturanalysen. Elektronenstruktur und Bindungsverhaltnisse in 1 -4 werden auf der Basis von MO-Modellrechnungen diskutiert.Bis(pentamethylcyclopentadienyl)germanium and -tin and … Show more

“…This interaction has been confirmed by x-ray analysis, but a theoretical analysis has not been carried out. Nevertheless, qualitative MO considerations have been reported [4,6,8,9]. In this case, the π-bonding HOMO of the aromatic system is stabilized by the atomic orbitals of the s 2 metal center of an appropriate symmetry, while the π ⁎ LUMO is not affected.…”

“…19 Following our established concept for the synthesis of VI (Fig. 1) equimolar amounts of amino(imino)germylene 1 and B(C 6 F 5 ) 3 were brought into contact in hexane solution (Scheme 2). After work-up 2 + [MeB(C 6 F 5 ) 3 ] − was obtained as a crystalline solid in moderate yield (48%).…”

“…In 1980 Jutzi et al [2] isolated the molecules Cp à 2 Ge (1) and Cp à 2 Sn (2) as the first representatives of bis(pentamethylcyclopentadienyl) compounds with elements of group 14. The synthesis of the corresponding lead compound Cp à 2 Pb (3) followed just one year later [3].…”
