A new structural supramolecular zinc(II) complex ( 1 ), [Zn(H 2 O) 6 ] 2+ [Zn(4,4′-bipy)(SO 4 ) 2 (H 2 O) 2 ] 2− [Zn(4,4′-bipy)(SO 4 )(H 2 O) 3 ] is synthesized in mixed solvent system at room temperature. The complex was characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. Structural analyses reveal that the complex is crystallized in the triclinic system with P 1 space group. Cell parameters: a  = 7.3145 (15) Å, b  = 11.194 (2) Å, c  = 11.442 (2) Å, α  = 72.48 (3)°, β  = 73.78 (3)°, γ  = 83.39 (3)°, V = 857.3 (3) Å 3 . Zn atoms (Zn1, Zn2 and Zn3) are all six-coordinated, however, the coordination environments of them are different. Owning to the abundant intro- and inter- hydrogen bonding interactions, the adjacent molecular units were connected to form a 2D supramolecular chain, and the two adjacent chains were furthermore linked to form a 3D supermolecular network structure via the hydrogen bonds. In addition, it is found that the complex has potential applications as fluorescent-emitting materials due to the strong fluorescence.
