Abstract
- A new Ce(III) complex of 5-aminoisophthalic acid (H 2 aip), [Ce(CH 3 COO)(aip)(H 2 O) 2 ]·H 2 O, has been prepared by single gel diffusion technique at room temperature using sodium metasilicate. The gel-grown crystals were characterised by CHN analysis, thermogravimetry, FT-IR and UV- Visible spectral studies. The single crystal X- ray diffraction studies reveal that the title compound crystallizes in monoclinic space group P 2 1 /c. CeO 9 polyhedra have distorted tricapped trigonal prism geometry and form edge sharing dimers. The adjacent dimers are connected by aip 2− in different directions and generate a three dimensional network structure with hydrophilic channels. The luminescent behaviour of the complex and the ligand were also investigated and the complex shows blue shifted emission. [ABSTRACT FROM AUTHOR]
