Compound Na3 [V2O3 (nta )2 ]·5H2O (1) (ntaH3 = N (CH2CO2H)3) has been prepared by reduction of a mixture of (NH4)2[VO(O2)2Cl] and H3(nta) in H2O with Na2S2O4. The compound crystallizes in the triclinic system, space group P1 with Mr = 685. 2, a = 11. 050(6), b=12. 179(4), c=9. 792 (3)A,α=111.71(2),β= 98. 23(3), γ= 89. 36(2)°, Z=2, V = 1210. 5A3,λ(MoKa) = 0. 71069 A, F(000) = 694 and DC = 1. 880g/cm3. The structure was solved by direct methods and refined by full-matrix least squares to final R and Rw values of 0. 055 and 0. 065, respectively.The structure of the anion can be considered as two [VO(nta)] fragments connected by one μ2-O atom. Each vanadium atom in the fragment is coordinated by one vanadyl oxygen atom, one bridging-oxygen atom, three oxygen atoms and one nitrogen atom from (nta) ligand in a distorted octahedral geometry. In this paper, we have studied the conversion of compound 1 to mononuclear compound Na2[VO(O2) (nta)]·5H2O (2) by oxidation with hydrogen peroxide, as well as thei
