Abstract<\/strong><\/p>\n

In this paper, the results of a systematic study of the reactivity of salicylaldoxime (C7<\/sub>H7<\/sub>NO2<\/sub>)(H2<\/sub>L1<\/sup>), with aqueous solutions of\u00a0 V(IV) using hydrothermal synthesis are reported.<\/p>\n

These reactions lead to the formation of gray-blue compounds\u00a0: (1) \u00a0\u00a0adduct\u00a0 of the formula Na4<\/sub>[V6<\/sub>IV<\/sup>V4<\/sub>V<\/sup>O22<\/sub>H2<\/sub>(OH)6<\/sub>(C7<\/sub>H6<\/sub>O2<\/sub>)2<\/sub>(C7<\/sub>H5<\/sub>NO)].6H2<\/sub>O (A1), (2) another adduct of formula H6<\/sub>[V3<\/sub>IV<\/sup>V7<\/sub>V<\/sup>O25<\/sub>(OH)3<\/sub> (C7<\/sub>H8<\/sub>NO2<\/sub>) (C7<\/sub>H5<\/sub>NO)2<\/sub>(C7<\/sub>H6<\/sub>O2<\/sub>)].5H2<\/sub>O\u00a0 (A2)\u00a0 and (3) a trimetric coordination complex of the formula\u00a0\u00a0\u00a0 [V3<\/sub>O5<\/sub>(C7<\/sub>H5<\/sub>NO)3<\/sub>(C7<\/sub>H4<\/sub>NO2<\/sub>)3<\/sub>(C7<\/sub>H7<\/sub>NO2<\/sub>)3<\/sub>]\u00b7(H2<\/sub>O) (C1).<\/p>\n

The obtained compounds\u00a0were characterized by means of elemental analysis, conductometry, UV-Visible, Fourier transform infrared absorption spectroscopy (FTIR), 1<\/sup>H and 51<\/sup>V nuclear magnetic resonance (NMR), EPR, magnetic measurements, mass spectroscopy and cyclic voltammetry.<\/p>\n
