Abstract: The title compound, di--chloro-bis[aquachloro(3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione)copper(II)], [Cu₂Cl₄(C₈H₁₀N₃O₂)₂(H₂O)₂], has the same chemical empirical formula as another compound [Bandoli et al. (1976). Inorg. Chim. Acta, 20, 71-78]. However, the title compound is a dimer arranged around an inversion centre, whereas Bandoli's compound is a chiral polymer. In the title compound, the Cu^II atom has a distorted tetragonal pyramidal coordination, formed by three Cl atoms, one N atom of the caffeine ligand and one O atom of a water molecule.
