Polymeric (ethylenediamine)silver(I) 2,4,6-trinitrophenolate

In the title compound, catena-poly[[silver(I)-mu-ethylenediamine] 2,4,6-trinitrophenolate], {[Ag(C2H8)](C6H2N3O7)}(n), the Ag atom is bicoordinated, in a linear configuration, by two different N atoms from two symmetry-related ethylenediamine ligands, resulting in a linear polymeric helical chain with an [- Ag - N - C - C - N -](n) backbone. In the crystal structure, the components are connected by weak interactions between Ag and O atoms from the phenolate anion and the nitro groups. There are also weak hydrogen-bonding interactions between the NH2 groups and some of the O atoms of the anions, forming a three-dimensional network.
