Abstract: | The title compound, {[Ag(C4H6NO4)(C4H5N3)]·H2O}n, was synthesized by the reaction of silver(I) nitrate with 2‐aminopyrimidine and iminodiacetic acid. X‐ray analysis reveals that the crystal structure contains a one‐dimensional ladder‐like AgI coordination polymer and that N—H...O and O—H...O hydrogen bonding results in a three‐dimensional network. The AgI centre is four‐coordinated by three N atoms from three different 2‐aminopyrimidine ligands and one O atom from one iminodiacetate ligand. Comparison of the structural features with previous findings suggests that the existence of a second ligand plays an important role in the construction of such polymer frameworks. |
