Synthesis, crystal structure and anti-tumor activity of a novel 3D supramolecular compound constructed from Strandberg-type polyoxometalate and benzimidazole

Compound 1 was composed of [HMo5P2O23]5 − polyanions and protonated biz cations, and five crystal water molecules, forming a 3D supramolecular structure. The experiment on anti-tumor activities in vitro showed that compound 1 inhibited human neuroblastoma SHY5Y cells and demonstrated dose dependency and selectivity.303
