摘要
Presented here is the preparation of oxovanadium silicate containing organic species as structural directing agents by using the solution preparative chemistry. The structure of this newly obtained oxovanadium silicate, [H3N(CH2)(2)NH3](2)[V(IV)(9)(OH)(8)(H2O)(12)(SiO4)(8)](H2O)(6) (1) has been determined by X-ray single crystal diffraction methods. The existence of a complex intercrossing channel system, including a very large channel of 18.4 A of diameter (in which both water molecules and ethylenediamine cation species are located), is the more interesting feature of this structure. The anticancer activity of compound 1 was then investigated against three human liver cancer cells (HB611, BEL-7402 and HHCC) by MTT assay. It was found that compound 1 showed potent antitumor activity against all of these cell lines.
