Reaction of Ba_0.50[Ag₂Cr(C₂O₄)₃]·5H₂O with Ag₂SO₄ in an aqueous solution of sulfuric acid (pH ≈ 3) yielded the silver(I)/chromium(III) oxalate salt H_0.50[Ag_2.50Cr(C₂O₄)₃]·5H₂O (1). Compound 1 can be best described as an anionic silver-deficient oxalatochromate(III) complex [Ag_2.50Cr(C₂O₄)₃]^0.5- with nanochannels containing hydrogen-bonded water molecules and protons. Thermal analyses show significant weight losses corresponding to the elimination of water molecules of crystallization followed by the decomposition of the network.
