Polymeric structure of (ethyl­ene­diamine)silver(I) 3‐nitro­benzoate monohydrate

In the ternary title compound, catena‐poly­silver(I)‐μ‐ethylenedi­amine‐κ²N:N′] 3‐nitro­benzoate monohydrate], {Ag(C₂H₈N₂)](C₇H₄NO₄)·H₂O}_n, the Ag atom is bicoordinated in a linear configuration by two different N atoms from two symmetry‐related ethyl­enedi­amine ligands, thus giving linear polymeric chains with an –Ag—N—C—C—N–]_n backbone running parallel to the a axis. In the crystal packing, these linear chains are interconnected by N—H?O and O—H?O hydrogen bonds to form layers parallel to the ab plane.
