A novel two-dimensional helical coordination polymer [Ag(CH(3)CN)(4)][Ag(3)(CH(3)CN)(8)(SiMo(12)O(40))] (1) has been gained by the conventional self-assembly reaction, and characterized by IR, elemental analysis, UV, TG technique and X-ray single crystal diffraction. Each [SiMo(12)O(40)](4-) cluster interconnects with three bimetallic cation subunits through three Mo-O-Ag bridges, meanwhile, each bimetallic cation subunit is surrounded by three [SiMo(12)O(40)](4-) to form an unprecedented two-dimensional network structure. The metal-metal bonds between Ag(1) and Ag(2) atoms from the adjacent helical chains connects the chains together into a chiral 2D helical network. The 2D network structures are further interconnected with each other to form a 3D supramolecular network through multiform intermolecular hydrogen bonds. The luminescent properties of the coordination polymer in the solid state were investigated.
