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
AgBF<sub>4</sub> in CHCl<sub>3</sub>/CH<sub>3</sub>CN resulted in
the formation of 1D straight-chain polymers. In the complexation of
the 3-pyridyl ligand with AgBF<sub>4</sub> in CHCl<sub>3</sub>/CH<sub>3</sub>CN, 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 AgSbF<sub>6</sub> in CHCl<sub>3</sub>/MeOH
