    Description / Table of Contents: Reactions and Thermal Behaviour of Nonoxo Vanadium(IV) Complexes. Crystal Structures of Methoxo-oxo[thenoyltrifluoroacetone-salicylhydrazonato(2-)]vanadium(V) and Methoxo-oxo[benzoylacetone-salicylhydrazonato(2-)]vanadium(V)The persistence of non-oxo vanadium(IV) complexes in dichlormethane/methanol/water solutions was studied by UV/VIS spectroscopy. The reaction products methoxo-oxo-[thenoyltrifluoroacetone-salicylhydrazonato(2-)]vanadium(V) and methoxo-oxo[benzoylacetone-salicylhydrazonato(2-)]vanadium(V) were isolated and characterized by X-ray analysis. The thermal behaviour of non-oxo vanadium(IV) complexes was checked.
    Notes: Die Beständigkeit oxofreier Vanadium(IV)-Komplexe mit dreizähnigen diaciden Liganden in Dichlormethan/Methanol/Wasser wurde UV/VIS-spektroskopisch untersucht. Als Reaktionsprodukte wurden Methoxo-oxo-[thenoyl-trifluoraceton-salicylhydrazonato(2-)]vanadium(V) sowie Methoxo-oxo-[benzoylaceton-salicylhydrazonato(2-)]vanadium(V) isoliert und röntgenstrukturanalytisch charakterisiert. Das thermische Verhalten der oxofreien Vanadium(IV)-Komplexe wurde analysiert.Methoxo-oxo-[thenoyltrifluoraceton-salicylhydrazonato(2-)]-vanadium(V), Raumgruppe P21/a2, Z = 4, 3 124 beobachtete unabhängige Reflexe, R = 0,0579, Gitterabmessungen bei 25°C; a = 800,0(2) pm, b = 2 027,3(6) pm, c = 1 165,0(3) pm, β = 109,03(2)° Methoxo-oxo-[benzoylaceton-salicylhydrazonato(2-)]vanadium(V) Raumgruppe P21/c, Z = 4, 2 312 beobachtete unabhängige Reflexe, R = 0,031, Gitterabmessungen bei 25°C: a = 1 122,6(1) pm, b = 772,96(9) pm, c = 2 021,2(4) pm, β = 95,32(1)°.
