Darstellung und Struktur der zweikernigen tert-Butyliminovanadium(IV)-Komplexe: [( t C 4 H 9 N) 2 V 2 Cp 2 X 2 ] (X = O t C 4 H 9 , Cl)

Abstract [(μ-N t C 4 H 9 ) 2 V 2 Cp 2 (O t C 4 H 9 ) 2 ] (2) and [(μ-Cl) 2 V 2 Cp 2 (N t C 4 H 9 ) 2 ] (6) have been prepared by reac­tion of Li t C 4 H 9 with t C 4 H 9 N=VCp(O t C 4 H 9 )Cl and t C 4 H 9 N=VCpCl 2 , respectively. The molecular structure has been investigated by X-ray diffraction analysis. NMR and ESR Spectra indicate two types of tert-butyliminovanadium(IV) complexes: 2 (diamagnetic) and 6 (paramagnetic).
