Abstract：A new molybdovanadophosphoric heteropoly compound containing glycine with tri-vanadium-substituted Dawson structure, namely C2H14O64P2Mo15V3·5H2O was synthesized and structurally characterized by elemental analysis, including IR spectra，X-ray and TGA powder diffraction. The median lethal dose (LD50) was 3 798.83 mg·kg-1, and the range of 95% confidence limit was 2 976.81-4 847.85 mg·kg-1. According to the study，this new compound may be regarded as a low toxic compound.
