摘要
The hydrothermal synthesis and crystal structures of four coordination polymers, namely, 2D [Zn(μ3-ta)(pytaH)]n (1), 2D [Zn(μ3-pyta)Cl]n (2), 1D [Cd(μ-pyta)2(H2O)]n (3), and 3D [Cd(μ3-pyta)(μ-Cl)]n (4) (pyta = (4-pyridylthio)acetate, ta = thioglycolate), are reported. They are based on (4-pyridylthio)acetate and its derived ligand. The ta2ligand present in 1 was generated from an in situ C(sp2)-S bond cleavage of the pyta ligand. In these compounds, versatile intermolecular interactions, such as close S…S interactions and strong (O―H…O/N/S) or weak (C―H…O/S, C―H…Cl) hydrogen bonding interactions, play an important role in the formation of three-dimensional supramolecular networks in the solid state.
The hydrothermal synthesis and crystal structures of four coordination polymers, namely, 2D [Zn（μ3-ta）（pytaH）]n （1）, 2D [Zn（μ3-pyta）Cl]n （2）, 1D [Cd（μ-pyta）2（H2O）]n （3）, and 3D [Cd（μ3-pyta）（μ-Cl）]n （4） （pyta = （4-pyridylthio）acetate, ta = thioglycolate）, are reported. They are based on （4-pyridylthio）acetate and its derived ligand. The ta^2- ligand present in 1 was generated from an in situ C（sp^2）-S bond cleavage of the pyta ligand. In these compounds, versatile intermolecular interactions, such as close S…S interactions and strong （O-H…O/N/S） or weak （C-H…O/S, C-H…Cl） hydrogen bonding interactions, play an important role in the formation of three-dimensional supramolecular networks in the solid state.
