Direct Synthesis of Cd3OSO4 Nano-particles From a New Three-dimensional Cadmium(II) Coordination Polymer Precursor

A new three-dimensional Cd(II) coordination polymer, {[Cd3(3-pyc)4(NCS)2(H2O)4]·2H2O}n (1); 3-Hpyc = 3-pyridinecarboxylic acid, was prepared and characterized by elemental analyses and IR spectroscopy. Compound 1 was structurally characterized by single-crystal X-ray diffraction. The structural determination shows that the compound is a new 3D coordination polymer has different environments containing CdO5NS and CdO2N4 units. This polymeric precursor has been used in the preparation of Cd3OSO4 nanoparticles by thermolysis in oleic acid. The new nano-structure of Cd3OSO4 was characterized by scanning electron microscopy and X-ray powder diffraction. This study demonstrates that coordination polymers may be suitable precursors to the preparation of desirable nanoscale materials.
