| Popis: | Çoban, Mustafa Burak A new terbium(III)-based 2D hydrogen-bonded polymer formulated as {[Tb-III (2-stp)(H2O)(3)].2(4,4'-bipy).5(H2O)}, (1) (4,4'-bipy = 4,4'-bipyridine and 2-stp = 2-sulfoterephthalate) was hydrothermally synthesized. This hydrogen-bonded Tb-III-based polymer was characterized by X-ray crystallography, spectroscopic, magnetic and photoluminescence measurements. Field emission scanning electron microscopy (FESEM) was used for the morphological analysis. The crystal structure of 1 shows a distorted square-antiprism geometry about Tb-III atom with two carboxylic oxygen atoms from the symmetry-related two 2-stp ligands and six oxygen atoms from the symmetry-related three coordinated water molecules. The magnetic behaviour of 1 reveals the antiferromagnetic interaction between Tb-III magnetic centers. The photoluminescence spectrum of 1 exhibits strong characteristic green emission bands of Tb-III with CIE chromaticity coordinates (0.185, 0.632). (C) 2018 Published by Elsevier B.V.
