Hydrothermal Syntheses and Photoluminescent Properties of Two Zinc(II) Coordination Polymers Based on 4,6-di(1H-imidazol-1-yl)-1,3,5-triazin-2-ol

摘要

Two new Zn(II) coordination polymers based on the tridentate ligand 4,6-di(1H-imidazol-1-yl)-1,3,5-triazin-2-ol (Hdit), namely, {[Zn(dit)(2)(H2O)(2)]center dot 4H(2)O}(n) (1) and [Zn(dit)(CH3COO)](n) (2), have been successfully constructed by varying the metal salts. Compound 1 shows 1D zigzag chain structure, and compound 2 is a 3D binodal (3,5)-connected architecture with {4(2)center dot 6(6)center dot 8(2)}{4(2)center dot 6} topology. The photoluminescent spectra indicate that at room temperature, compounds 1 and 2 emit violet and blue luminescence, respectively.
