In this work, three new vanadium complexes are reported. Their synthesis, crystallization and characterization are detailed. The complex (1) [VO(C7H6NO2)2] is a mononuclear and crystallizes in the monoclinic P21/n space group exhibiting a square pyramidal geometry around the vanadium. Dissolved in p-xylene (1–4 dimethylbenzene), this complex gives a binuclear complex (2) [V2O2(C7H6NO2)2(C7H5NO2)2]·C8H10 with a triclinic P-1 space group and an octahedral geometry around the vanadium. The complex (3) [VO2(C9H9N2O3)] was obtained using the new iminoacylated oxime ligand (the result of the nucleophilic attack of 4-hydroxysalicylaldoxime with acetonitrile), it crystallizes in the triclinic P-1 space group with a trigonal bipyramidal geometry around the vanadium. All complexes were characterized by single crystal X-ray diffraction, FT-IR, NMR, UV–visible and TGA.
