title: Bis(imidazo[1,2-a]pyridin-1-ium) tetra-chlorido-cuprate(II) dihydrate.
abstract: In the title salt, (C7H7N2)2[CuCl4]·2H2O, the Cu2+cation is coordinated by four Cl atoms and adopts a distorted tetra-hedral geometry. Two mol-ecules of imidazo[1,2-a]pyridine are protonated ensuring electrical neutrality. O-H⋯Cl and N-H⋯O hydrogen bonds link the organic and the inorganic moieties, leading to a self-organized hydrated hybrid structure.
