(μ-5-Carb­oxy-1H-imidazole-4-carboxyl­ato-κ4N1,O5:N3,O4)bis­[amminesilver(I)]

摘要

In the title compound, [Ag2(C5H2N2O4)(NH3)2], each of the two Ag^I 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—H⋯O hydrogen bond.
