Abstrakt: The crystal structure of hexa-glycinium tetra-μ-iodido-octa-iodido-triplumbate, (C 2 H 6 NO 2 ) 6 [Pb 3 I 12 ] or (GlyH) 6 [Pb 3 I 12 ], is reported. The compound crystallizes in the triclinic space group P . The [Pb 3 I 12 ] 6- anion is discrete and located around a special position: the central Pb ion located on the inversion center is holodirected, while the other two are hemidirected. The supra-molecular nature is mainly based on C-H⋯I, N-H⋯I, O-H⋯I and N-H⋯O hydrogen bonds. Dimeric cations of type ( A + ⋯ A + ) for the amino acid glycine are observed for the first time.
