Popis: WOS: 000434792900014 Gd(III) ions display fascinating luminescence properties. Therefore, a new two dimensional polymeric Gd(III) complex, {[Gd(2-stp)center dot 3(H2O)]center dot(H2O)}(n), [2-stp = 2-sulfoterephthalate] has been synthesized under hydrothermal conditions and characterized by elemental analysis, FT-IR, UV-visible and single-crystal X-ray diffraction and solid state photoluminescence measurements. The crystal structure of the Gd complex shows that Gd atom is coordinated to eight oxygen atoms by four symmetry-related 2-stp ligands and three coordinated water molecules to form a distorted square-antiprismatic geometry. The 2-stp ligand coordinates to four different Gd atoms and acts as a A mu(4)-bridging ligand, end up with a two-dimensional layer structure. Moreover, 2D layer structure with hydrogen bonding interactions may develop the decisiveness of the crystal structure of Gd complex and achieve a 3D architecture. In addition, the solid state photoluminescence spectra show that Gd complex exhibited a strong green emission when it is excited under UV light at 349 nm.

The author is also very grateful to Dr. M. Burak Coban (Balikesir University, BUBTAM) for the photoluminescence measurement and to Dr. Hulya Kara Subasat (Mugla Sitki Kocman University) for the useful and constructive recommendation.
