Synthesis, Structure Characterization and Biological Activity of a Novel Polyoxovanadate Cluster: [NH3(CH2)2NH2(CH2)2NH3
A new polyoxovanadate cluster,[NH3(CH2)2NH2(CH2)2NH3]4[VⅤ6VⅣ12O42(PO4)](PO4)·2H2O, has been synthesized and characterized by means of elemental analysis, IR spectrometry, EPR spectrometry, TG analysis and single crystal X-ray diffraction. This compound crystallizes in a monoclinic space group C2/c with a=2.3912(5) nm, b=1.3002(3) nm, c=2.0172(4) nm, β=105.75(3)°, V=6.036(2) nm3, Z=2, R1=0.0572, wR2=0.1476. It has a superKeggin structure with a Keggin unit capped by six [VO5] moieties on the pits on every side of the Keggin unit. The anti-tumor activity of the compound was estimated in three human tumor cell lines in vitro.
