A new inorganic-organic open framework based on Wells-Dawson arsenomolybdate, {Ag(diz)2}3[{Ag(diz)2}3(As2Mo18O62)]∙H2O (1) (diz=1,2-diazole) has been hydrothermally synthesized and characterized by elemental analysis, IR, TG, UV, XRD, and single-crystal X-ray diffraction. In compound 1, each {As2Mo18} cluster uses six terminal oxygen atoms on 'equator' position to attract peripheral six {Ag(diz)2} linkers, which are further connected by six Dawson clusters located on two different planes via unique equator-to-equator interlaced ways to form a unprecedented 3D network with {812∙123}{8}3 topology. Compound 1 represents the highest covalent connectivity of 3-D Dawson arsenomolybdate, which exhibits merit photocatalytic properties for degradation of refractory dyes Azon Phloxine (AP) under UV light. In addition, compound 1 has a potent inhibition effect on proliferation of Human gastric adenocarcinoma cells (SGC-7901). The silver organic complex linkers {Ag(diz)2} are introduced into {As2Mo18} systems, leading to unprecedented 3-D network with {812∙123}{8}3 topology, which represents the highest covalent connectivity of 3-D Dawson arsenomolybdate. The compound exhibits high-efficient degradation ability for refractory dyes AP and potent inhibition effect on proliferation of SGC-7901 cells.
