catena-poly[[μ-ethylenediamine-κ2N:N′-bis[(ethylenediamine-κ2 N,N′)silver(I)]bis[silver(I)-μ-barbiturato-2N:N′]] dihydrate]

The title compound, {[Ag-2(C2H8N2)(3)][Ag-2(C8H10-N2O3)(2)].2H(2)O}(n), consists of one-dimensional polymeric silver(I) complex anionic chains, discrete dinuclear silver(I) complex cations and solvent water molecules. In the anionic chain, each Ag-I atom is coordinated by two deprotonated N atoms from two barbiturate ligands in a perfectly linear geometry. In the dinuclear silver(I) complex cation, each Ag-I atom, in a Y-shaped coordination environment, is coordinated by three N atoms from two ethylenediamine molecules. The bridging ethylenediamine ligand and the Ag atoms of the anionic chain lie on inversion centres.
