| Abstract: | A new structural supramolecular zinc(II) complex (1), Zn(H2O)6]2+Zn(4,4′-bipy)(SO4)2(H2O)2]2?Zn(4,4′-bipy)(SO4)(H2O)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 P1 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) Å3. 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. |
