Three-dimensional silver(I) co-ordination polymer with pocket structures

Abstract

Silver(I) complexes of hexakis(phenylsulfanyl)benzene (hphb), [Ag₂(hphb)][PF₆]₂1 and [Ag(hphb)(NO₃)] 2, have been prepared and their molecular structures determined by X-ray crystallography. In 1 the silver ion adopts a tetrahedral co-ordination geometry comprising four S atoms from two different hphb molecules and giving an eight-membered Ag–S ring structure in a co-ordination polymer. This ring (6.46 × 6.79 Å) forms a three-dimensional framework with pockets. On the other hand, for 2, the silver(I) ion has a square pyramidal environment with four S atoms and one O atom of a NO₃⁻ anion. The complex forms a linear-chain structure with an alternating arrangement of silver ions and hphb.
