Synthesis, crystal structure, and luminescence properties of a new calcium(II) coordination polymer based on L-malic acid

Abstract

A new calcium coordination polymer [Ca(HL-MA)]n (H 3L-MA = L-malic acid) has been solvothermally synthesized. The structure of the newly synthesized complex has been determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, reflectance UV-Vis & IR spectra, powder X-ray diffraction (PXRD), and thermogravimetric analysis (TGA). The single crystal structure analysis showed that the complex forms three-dimensional framework. The new Ca(II) complex has displayed very high thermal stability which was inferred from TGA and PXRD results. As far as the optical property of the new complex is concerned, the complex emitted its own characteristic sensitized luminescence. © 2013 Duraisamy Senthil Raja et al.
