Bis(imidazo[1,2-a]pyridin-1-ium) tetrachloridocuprate(II) dihydrate

Abstract

In the title salt, (C7H7N2)2[CuCl4]·2H2O, the Cu2+cation is coordinated by four Cl atoms and adopts a distorted tetrahedral geometry. Two molecules 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.
