A novel three‐dimensional AgI coordination polymer based on mixed naphthalene‐1,5‐disulfonate and aminoacetate ligands

The three-dimensional coordination polymer poly[[bis­(μ3-2-amino­acetato)di-μ-aqua-μ3-(naphthalene-1,5-di­sulfonato)-hexa­silver(I)] dihydrate], {[Ag6(C10H6O6S2)(C2H4NO2)4(H2O)2]·2H2O}n, based on mixed naphthalene-1,5-di­sulfonate (L1) and 2-amino­acetate (L2) ligands, contains two AgI centres (Ag1 and Ag4) in general positions, and another two (Ag2 and Ag3) on inversion centres. Ag1 is five-coordinated by three O atoms from one L1 anion, one L2 anion and one water mol­ecule, one N atom from one L2 anion and one AgI cation in a distorted trigonal–bipyramidal coordination geometry. Ag2 is surrounded by four O atoms from two L2 anions and two water mol­ecules, and two AgI cations in a slightly octa­hedral coordination geometry. Ag3 is four-coordinated by two O atoms from two L2 anions and two AgI cations in a slightly distorted square geometry, while Ag4 is also four-coordinated by two O atoms from one L1 and one L2 ligand, one N atom from another L2 anion, and one AgI cation, exhibiting a distorted tetra­hedral coordination geometry. In the crystal structure, there are two one-dimensional chains nearly perpendicular to one another (inter­chain angle = 87.0°). The chains are connected by water mol­ecules to give a two-dimensional layer, and the layers are further bridged by L1 anions to generate a novel three-dimensional framework. Moreover, hydrogen-bonding inter­actions consolidate the network.
