SYNTHESIS, STRUCTURE, THERMAL STABILITY AND FLUORESCENCE OF A NEW CADMIUM(II) COORDINATION POLYERS AS PRECURSOR FOR PREPARATION OF CdO MICRO-CRYSTAL
A new complex [Cd(btca)0.5(H2O)3] (1) (H4btca: 1,2,4,5-benzenetetracarboxlyic acid) has been synthesized and characterized by single crystal X-ray diffraction studies, elemental analysis and FT-IR. In compound 1, Cd(II) center atoms coordinate to three ligand btca4- anions and three water molecules with a six-coordinated distorted octahedral geometry. Four carboxyl groups of btca4- adopt μ2-η2:η0 and μ1-η1:η0 two different coordination modes. The whole anion btca4- acts as a hexadentate bridge to connect adjacent Cd(II) atoms, resulting in 2D layer structure. Further, these two-dimensional layers are linked together by O-H···O to give rise to three-dimensional structure. Thermal stability and luminescent property of 1 are investigated. CdO micro-crystalline particles are then produced by calcination of compound 1 at 580 ºC. The obtained CdO is characterized by XRD and SEM analyses.
