Poly[[{?(3)-2-[4-(2-hy-droxy-eth-yl)piperazin-1-yl]ethane-sulfonato}-silver(I)] trihydrate].

ABSTRACT: Ethane-sulfonic acid-based buffers like 2-[4-(2-hy-droxy-eth-yl)-piperazin-1-yl]ethane-sulfonic 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(C(8)H(17)N(2)O(4)S)]·3H(2)O}(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 inter-actions from the hy-droxy and sulfate O atoms of HEPES complete a distorted seesaw geometry. The crystal structure is stabilized by O-H?O hydrogen-bonding interactions.
