摘要

The hydrothermal reactions of sodium o-hydroxybenzoate with AgNO3 yield a novel stable Ag(I) σ-complex supramolecular polymer, [Ag2(o-HOPhCO2)2]n. The structure of [Ag2(o-HOPhCO2)2] was solved by single crystal X-ray diffraction analysis. It is monoclinic with space group P21/c and unit cell parameters a=0.7394(2) nm, b=0.8822(2) nm, c= 1.0662(2) nm, β= 107.66(3)°, Z=4. The silver(I) atom is two-coordinated by two carboxylic oxygen atoms of two o-hydroxybenzoate ligands, and meanwhile, forms supramolecular interaction with one carbon atom of phenyl-ring in the third o-hydroxybenzoate group. The σ-form Ag…C supramolecular bond bridges [Ag2(o-HOPhCO2)2] units into an infinite 2D layered polymer [Ag2(o-HOPhCO2)2]n. The coordination sphere of the silver atom is best described as a distorted T-shaped geometry.
