A novel silver(I) s̀‐complex supramolecular polymer: [Ag 2 (o‐HOPhCO 2 ) 2 ] n

The hydrothermal reactions of sodium o‐hydroxybenzoate with AgNO 3 yield a novel stable Ag(I) s̀‐complex supramolecular polymer, [Ag 2 ( o ‐HOPhCO 2 ) 2 ] n. The structure of [Ag 2 ( o ‐HOPhCO 2 ) 2 ] was solved by single crystal X‐ray diffraction analysis. It is monoclinic with space group P2Jc 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 a‐form Ag…C supramolecular bond bridges [Ag 2 ( o ‐HOPhCO 2 ) 2 ] units into an infinite 2D layered polymer [Ag 2 ( o ‐HOPhCO 2 ) 2 ] n . The coordination sphere of the silver atom is best described as a distorted T‐shaped geometry.
