Abstract
The complex, disodium aquabis(malonato)oxovanadate(IV) monohydrate, has been synthesized and its structure determined by X-ray diffraction analysis. The geometry around the metal is octahedral and the two malonate ligands are coordinated in a trans-arrangement with respect to one another, forming an equatorial plane, with oxo and aqua ligands occupying the axial positions. The V=O bond length is 1.596(2) Å and the four equatorial V–O distances range between 1.995(2) and 2.012(2) Å. An intensive network of weak hydrogen bonds is observed between crystalline water molecules and between oxygen atoms of the anion and sodium cations.
