Ethanesulfonic acid-based buffers like 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid (HEPES) are commonly used in biological experiments because of their ability to act as non-coordinating ligands towards metal ions. However, recent work has shown that some of these buffers may in fact coo...

Description
Summary:Ethanesulfonic acid-based buffers like 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid (HEPES) are commonly used in biological experiments because of their ability to act as non-coordinating ligands towards metal ions. However, recent work has shown that some of these buffers may in fact coordinate metal ions. The title complex, {[Ag(C8H17N2O4S)]·3H2O}n, is a metal–organic framework formed from HEPES and a silver(I) ion. In this polymeric complex, each Ag atom is primarily coordinated by two N atoms in a distorted linear geometry. Weaker secondary bonding interactions from the hydroxy and sulfate O atoms of HEPES complete a distorted seesaw geometry. The crystal structure is stabilized by O—H...O hydrogen-bonding interactions.
