Synthesis and crystal structure of a novel two-dimensional corrugated coordination polymer

Assembly of 4-aminosalicyclic acid (H2L) and Ag(I) in MeCN/H2O gave rise to a novel corrugated sheet polymer {[Ag(HL−)]·H2O}n. X-ray structural analysis reveals that Ag(I) is coordinated by three different HL− ligands in a distorted trigonal geometry and HL− links three different Ag(I) in a μ3-bridge mode forming a two-dimensional sheet structure with curvature. The separation of the carboxylate-bridged Ag⋯Ag and the distance of adjacent sheets are 2.7720(6) and 4.24 Å, respectively.
