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, R_1=0.0572, wR_2=0.1476. It has a superKeggin structure with a Keggin unit capped by six [VO_5] 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.展开更多
