-5-Carboxy-1H-imidazole-4-carboxylato-![[kappa]](/logos/entities/kappa_rmgif.gif)
4N1,O5:N3,O4)bis[amminesilver(I)]Abstract: In the title compound, [Ag2(C5H2N2O4)(NH3)2], each of the two AgI atoms is coordinated by two N atoms from an ammonia molecule and a 5-carboxy-1H-imidazole-4-carboxylate ligand in an almost linear geometry, and by one carboxylate O atom with a weak interaction. The Ag atoms are assembled into a linear tetramer through Ag
Ag interactions. Each Ag tetramer is linked by four 5-carboxy-1H-imidazole-4-carboxylate ligands, forming a puckered chain. The complex involves a strong intramolecular O-HO hydrogen bond.
