Synthesis, Structure, and Thermal Stability of Silver(I) Coordination Polymers with Bis(pyridyl) Ligands Linked by an Aromatic Sulfonamide: One-Dimensional-Straight Chain, One-Dimensional-Columnar with Helical Components, and Two-Dimensional-Layer Network Structures

Abstract

Three different types of coordination polymers, one-dimensional (1D) straight chain, 1D-columnar structure, and two-dimensional (2D) layer structure, have been prepared by the complexation of Ag(I) ions with bis(pyridyl) ligands linked by an aromatic sulfonamides and structurally characterized by single-crystal X-ray diffraction and thermogravimetric analysis. Structural analyses showed that the complexation of the 3-pyridyl ligand with AgOTf and the complexation of the 4-pyridyl ligand with AgBF4 in CHCl3/CH3CN resulted in the formation of 1D straight-chain polymers. In the complexation of the 3-pyridyl ligand with AgBF4 in CHCl3/CH3CN, the resulting continuous 1D columnar coordination polymers were formed containing a racemic mixture of left- and right-handed helices. Furthermore, the 2D-layer structure was constructed by the complexation of a 4-pyridyl ligand with AgSbF6 in CHCl3/MeOH.
