Synthesis, Characterization and Crystal Structure of Coordination Polymers Developed as Anion Receptor

摘要

Reaction of diamide ligand, namely N, N'-2, 6-bis(4-pyridylmethyl)pyridine dicarboxamide (L) with cadmium nitrate and cadmium perchlorate has given rise to the formation of two types coordination polymers. Compound (CP1-Cd) with formula molecule {[Cd(L)_2(H_2O)_2](NO_3)_2·6H_2O}_n is a one-dimensional coordination polymer while compound (CP2-Cd), with formula molecule {[Cd(L)_2(H_2O)_2](ClO_4)_2·31/2H_2O·CH_3OH}_n, is a two dimensional coordination polymer. These coordination polymers were prepared via slow evaporation methods and completely characterized by combination of solid state techniques such as Fourier Transform Infrared (FTIR) spectroscopy, elemental analysis and X-ray crystallography. This study revealed that coordination polymers derived from N, N'-2, 6-bis(4-pyridylmethyl)pyridine dicarboxamide can accommodate anions with different sizes, showing good potential as anion receptor.
