catena-Poly[[-ethylenediamine-²N:N'-bis[(ethylenediamine-²N,N')silver(I)] bis[silver(I)--barbiturato-²N:N']] dihydrate]

Z.-D. Liu and H.-L. Zhu

Abstract: The title compound, {[Ag₂(C₂H₈N₂)₃][Ag₂(C₈H₁₀N₂O₃)₂]·2H₂O}_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.
