Abstract
Two new coordination polymers, [ZnL] n (1) and {[Zn(phen)(L)(H2O)] · 3H2O} n (2) (H2L = 1,2-bis[3-(1,2,4-triazolyl)-4-amino-5-carboxylmethylthio]ethane, phen = 1,10-phenanthroline), have been synthesized and characterized by elemental analysis, IR, and X-ray diffraction. Polymer 1 is a 1-D infinite chain (space group P 1) and further forms a 3-D supramolecular structure by S ··· S interactions and hydrogen bonds. Polymer 2 displays a mononuclear structure (space group P 1) and extends into a 3-D supramolecular structure through hydrogen bonds. In addition, spectra and thermal stability of 1 and 2 are also discussed. Strong luminescence characteristics of both polymers are found, suggesting their potential applications as luminescent materials.
