Abstract:

A novel supramolecular compound with the formula [Ni(C8N3H7)3]4[Mo8O26]2·7H2O was synthesized by the hydrothermal reaction of (NH4)2[Mo4O13]·2H2O, NiCl2·6H2O and [2-(1H-pyrazol-3-yl)-pyridine].The inorganic-organic hybrid material was characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. The results of X-ray diffraction indicate that the title complex contains both α- and β-octamolybdates. Leading to the connection between the [Ni(C8N3H7)3]2+ complex cation and [Mo8O26]4- through hydrogen bonding interactions, and the connection between the complex cation [Ni(C8N3H7)3]2+ groups through π-π stacking interactions between aromatic rings, two kinds of octamolybdate anions as guests were accommodated in a 3D “honeycomb” host supramolecular network. Therefore, in vitro anti-tumor activity of the compound on human ovarian cancer cells SK-OV-3, human lung cancer cells A549, human cervical cancer cells Hela and human breast cancer cells MCF-7 was studied. The results show that the compound has a certain degree of growth inhibition to three different sources of tumor cells. In particular, the IC50 value to the MCF-7 cells is 6.48 μmol /L, it shows that the compound has the value for further study.
