Abstract

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.

Highlights

Metal-organic coordination polymers have received great attention as an important part of coordination chemistry
Many of them that are constructed by Cd(II) ions or bridging multipodal ligands show unique structures and excellent properties in gas storage, luminescence, catalysis, and magnetism [1,2,3,4,5,6,7]
N-nicotinoylglycine ligand absorption and Cd(II) bands complex was conducted with infrared data, and the ligand two characteristic at 1725 cm−1

Summary

Introduction

Metal-organic coordination polymers have received great attention as an important part of coordination chemistry. Many of them that are constructed by Cd(II) ions or bridging multipodal ligands show unique structures and excellent properties in gas storage, luminescence, catalysis, and magnetism [1,2,3,4,5,6,7]. In order to investigate the coordination behavior of ligands containing both −COO− and pyridine bifunctional groups and the property of their metal complexes, a new 1D Cd(II) coordination polymer, [{CdL2 (H2 O)}·(H2 O)3 ]n (HL = N-nicotinoylglycine) has been synthesized and its luminescent property in the solid state has been investigated. The chemical diagram of the Cd(II) complex is shown in Scheme 1. 1. Chemical diagram of the Cd(II) complex
