title: Synthesis, structural determination and spectroscopic analysis of a novel 2D terbium coordination network with ethyleneglycol-bis-(2-aminoethylether)-N,N,N',N'-tetraacetic acid.
abstract: A novel two-dimensional (2D) mononuclear complex, namely, (enH(2))[Tb(III)(egta)(H(2)O)](2)·6H(2)O (H(4)egta=ethyleneglycol-bis-(2-aminoethylether)-N,N,N',N'-tetraacetic acid and en=ethylenediamine), was successfully synthesized and characterized by infrared spectrum, UV-vis spectrum, fluorescence spectrum, thermal analysis and single-crystal X-ray diffraction techniques. Single-crystal X-ray diffraction analysis reveals that the central Tb(III) ion is nine-coordinate in geometry of pseudo-monocapped square antiprismatic polyhedron. Furthermore, the hydrogen bonds play an important role in the fabrication of layer structure of the complex. Through hydrogen bonds between ethylenediamine cation (enH(2)(2+)) and [Tb(III)(egta)(H(2)O)](-) complex anion, the title complex forms a 2D layer network along [111] crystallographic direction. Particularly, the fluorescent property is also fully investigated, which indicates that the title complex would be a potential candidate as fluorescent materials.
