Abstract: | In 1‐naphthylammonium iodide, C10H10N+·I?, and naphthalene‐1,8‐diyldiammonium diiodide, C10H12N22+·2I?, the predominant hydrogen‐bonding pattern can be described using the graph‐set notation R42(8). This is the first report of a structure of a diprotonated naphthalene‐1,8‐diyldiammonium salt. |
