Source of material

An amount of 1.38 g 5-aminonicotinic acid was added to 15 mL 30% hydroiodic acid solution and stirred for 10 min at room temperature; then filtered. The filtrate was allowed to evaporate in open air. Yellow crystals were obtained after five days, yield 69% (based on 5-aminonicotinic acid).

Experimental details

The structure was solved by direct methods with the SHELXS program. All H-atoms from C and N atoms were positioned with idealized geometry (Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.2Ueq(N)) using a riding model with C–H = 0.95 Å and N–H = 0.88 to 0.885 Å. Also the H atom at O1 was included using a riding model with the O–H distance of 0.84 Å(Uiso(H) = 1.5Ueq(O)).

Comment

Aminonicotinic acid and its derivatives can act as organic ammonium cations with inorganic anions to make organic ammonium salts, such as 2-amino-3-carboxypyridin-1-ium salts [5], [6], [7] and 3-amino-5-carboxypyridin-1-ium salts [8], [9], [10], [11], [12], [13], [14], [15], [16]. To the best of our knowledge, except some 3-aminonicotinic acid containing metal complexes [17], [18], [19], [20], [21], [22], only one example of a 3-aminonicotinic acid based salt, the 3-amino-5-carboxypyridin-1-ium perchlorate monohydrate, has been reported [22]. Thus, we report the crystal structure of 3-amino-5-carboxypyridin-1-ium iodide.

The asymmetric unit of the title structure is made of one 3-amino-5-carboxypyridin-1-ium cation and one idodide anion. The N atom from the pyridine ring is protonated, while the NH2 group keeps as it is. The organic cations are linked by hydrogen bonds N1–H1A⃛O2 to generate one-dimensional chains, further forming two-dimensional double planes by the hydrogen bond N2–H2B⃛O1 and C3–H3⃛O1, and finally building a three-dimensional supramolecular structure by weak ππ and H⃛I interactions. The iodide anion is regulated by weak interactions O1–H1⃛I1, N2–H2A⃛I1, C5–H5⃛I1, and C7–H7⃛I1. All bondlengths are normal and comparable with the reported results [15, 22].
