Synthesis, structure characterization and biological activity of layered vanadium oxides [NH3 (CH2)2 NH (CH2)2 NH3][V6O14]

A new layered vanadium oxide [NH3(CH2)(2)NH(CH2)(2)NH3] [V6O14] (compound 1) was synthesized and characterized by elemental analysis, IR spectrometry and single crystal X ray diffraction. The compound crystallizes in a monoclinic space group P2 (1)/n with a 1.0254 ( 2) nm, b = 0.6739 ( 2) nm, c = 1.2400 ( 2) nm, beta = 93.88 (3)degrees, V = 0.8549 (3) nm(3), Z = 2, R-1 = 0.0366, wR(2) = 0.1038. Compound 1 consists of two-dimensional mixed-valence vanadium oxide layers parallelling to the bc plane. The anti-tumor activity of the compound was estimated in three human tumor cell lines in vitro.
