Abstract: The oxalatooxoperoxovanadates(V) (H₃dien)[VO(O₂)(C₂O₄)₂] ·H₂O (I), (H3tren)[VO(O₂)- (C₂O₄)₂] · 3H₂O (II ), (Hampic)₃[VO(O₂)(C₂O₄)₂] ·2H₂O (III ), and (Hampic)₃[VO(O₂)₂(C₂O₄)] · 4H₂O (IV ) (dien = diethylenetriamine, tren = tris(2-aminoethyl)amine, ampic = 2-amino-3- methylpyridine) have been prepared and characterized by elemental analyses and IR spectroscopy. Based on the position and intensity of the characteristic infrared bands, the usual monomeric pentagonal bipyramidal structure for anions in I—IV can be proposed. The proposed structure was confirmed for II by X-ray diffraction study. II crystallizes with triclinic cell a = 895.8(2) pm, b = 899.3(3) pm, c = 1207.6(3) pm, α = 93.25(2)º, β = 99.31(2)º, γ = 90.86(2)º, space group P-1, Z = 2.
