Synthesis, Crystal Structure, and Luminescent Property of a Cd(II) Coordination Polymer with a N-Nicotinoylglycine Ligand

A new 1D Cd(II) coordination polymer, [{CdL2(H2O)}·(H2O)3]n (HL = N-nicotinoylglycine), has been synthesized by the assembly of Cd(NO3)2·4H2O with N-nicotinoylglycine, and its composition was determined by elemental analysis, infrared, and X-ray single-crystal diffraction analysis. In this complex, the Cd(II) is seven-coordinated by two N atoms of two N-nicotinoylglycine anions, four O atoms of two N-nicotinoylglycine anions, and one O atom of a coordinated water molecule. The complex forms a 1D looped coordination polymer by the bridging of the N-nicotinoylglycine anion. The luminescent property of the N-nicotinoylglycine ligand and the Cd(II) coordination polymer has also been studied.
