Darstellung und NMR-spektroskopische Untersuchung eines hexakoordinierten p-Tolylo-tantal(V)-Komplexes: [(p-CH3C6H4)5 Ta(p-CH3C6H4)Li · O(C2H5)2]

Preparation and N.M.R.-spectroscopie Investigation of a Hexacoordinated p-Tolylotantalum(V) Complex: [(p-CH₃C₆H₄)₅Ta(p-CH₃C₆H₄)Li · O(C₂H₅)₂] Reaction of tantalum(V) bromide with an etheral solution of p-tolyllithium in the molar ratio 1:5 leads to precipitation of a yellow complex of the brutto formula LiTaTol₆ · Ae[Tol = p-CH₃C₆H₄^?; Ae = (C₂H₅)₂O]. The ¹H and ¹³C n.m.r. spectra are discussed.
