Abstract: In the title compound, (2-amino-4,6-dimethylpyridinium) diiodocuprate(I), (C₇H₁₁N₂)[CuI₂], the planar 2-amino-4,6-dimethylpyridine species is protonated at the pyridine N atom. It interacts with the inorganic chains by extensive hydrogen bonding. The cation forms N-HI hydrogen bonds from both its pyridine and amine N atoms. The copper(I) species is tetrahedrally bonded to four iodide ions (average Cu-I distance = 2.665  Å, with a standard uncertainty of 0.019  Å) and forms infinite edge-sharing chains. Atom-site symmetries: Cu (2); I, phenyl-C and N (m).
