Non-oxo Vanadium(IV) Complexes with Tridentate Diacidic Ligands. Molecular Structure of Bis[2.2′-dihydroxy-azobenzenato(2-)]vanadium(IV)By the reaction of tris(acetylacetonato)vanadium(III) with tridentate diacidic ligands non-oxo vanadium(IV) complexes of these ligands were synthesized. The complexes were characterized by mass spectrometry. Electrochemical studies show that the complexes are reversibly oxidized or reduced. Bis[2,2′-dihydroxy-azobenzenato(2-)]vanadium(IV) has a distorted trigonal-prismatic structure. Crystallographic data see „Inhaltsübersicht“.
Notes:
Durch Reaktion von Tris(acetylacetonato)-vanadium(III) mit dreizähnigen diaciden Liganden wurden oxofreie Vanadium(IV)-Komplexe dieser Liganden dargestellt. Die Komplexe wurden massenspektrometrisch charakterisiert. Sie können elektrochemisch reversibel oxidiert und reduziert werden. Bis[2,2′-dihydroxy-azobenzenato(2-)]vanadium(IV) besitzt eine verzerrt trigonal-prismatische Struktur. Raumgruppe P21/n, Z = 4, 1 812 beobachtete unabhängige Reflexe, R = 5,9%. Gitterabmessungen bei 19°C; a = 9,973(2) pm, b = 15,435(3) pm, c = 13,763(3) pm, β = 104,79(3)°.
