Abstract: In the crystal structure of the yellow copper(I) compound, {[Cu₂(SO₄)(C₁₀H₈N₂)₂]·4H₂O}_n, one [(C₁₀H₈N₂)₂Cu]_n chain is stacked over another [CuCu = 3.180 (1) Å]; the two chains are bridged by SO₄ groups through two Cu-O bonds into a double-chain motif. The SO₄ groups are located alternately on opposite sides of the double chain and lie on twofold rotation axes. The disordered solvent water molecules occupy the space between the double chains. The Cu^I atom exists in a T-shaped environment.
