Abstract: A new 3D supramolecular compound,(4,4’-bipy)[Ag(4,4’-bipy)]3[PMo12ⅥO40]·H2O(1) was synthesized under mild hydrothermal condition, and the structure was characterized by elemental analysis, single crystal X-ray diffraction, IR and TGA. Compound 1 exhibits a photoluminescence property at room temperature. The structure of this compound consists of [PMo12O40]3- anion, which is further connected by [Ag(4,4’-bipy)]3+ unit to form a three-dimesional supramolecular network. Compound 1 crystallized in the triclinic system, space group P1, a=1.1275(2) nm, b=1.1910(2) nm, c=1.2898(3) nm, α=112.63(3)°, β=94.63(3)°, γ=99.53(3)°, V=1.5567(5) nm3, Z =1.
