Abstract:
The title compound, (NH4)2[VO(C3H2O4)2]·2H2O, crystallizes in the monoclinic space group P21/n, with a=7.1889(7), b=19.254(2), c=9.879(2) Å, β=108.19(1)o, and Z=4. The VO2+ cation is five-fold coordinated with two malonate anions acting as bidentate ligands and a water molecule. Infrared and Raman spectra are also reported to attain a wider insight into the compound characteristics.
Keywords:Bis(malonato)oxovanadium(IV)  crystal structure  IR and Raman spectra
