Abstract:
A new molybdovanadophosphoric heteropoly compound containing glycine with tri-vanadium-substituted Dawson structure, namely C2 H14O64P2Mo1515V3 x 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 x kg(-1), and the range of 95% confidence limit was 2 976. 81-4 847. 85 mg x kg(-1). According to the study, this new compound may be regarded as a low toxic compound.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
