[online]. 2015, vol.115, n.10, pp.957-960. ISSN 2411-9717.  https://doi.org/10.17159/2411-9717/2015/v115n10a9.

The tetraethylammonium salt of the mono-anionic coordination compound me/^--oxidotrichlorido(thenoyltrifluoroacetylacetonato-K²O,O')niobate(V) (NEt₄)[NbOCl₃](ttfa)], has been prepared under aerobic conditions and characterized by single-crystal X-ray diffraction. (NEt₄)[NbOCl₃](ttfa)] crystallized in the monoclinic .P2i/c space group, with a = 11.483 (5), b = 12.563 (5), c = 17.110(5) Â, and β = 100.838 (5)°. The complex structure exists in a 50.0% (N^bA) : 50.0% (N^bB) positional disorder ratio.

Palavras-chave : Bidentate; niobium(V); disorder.
