Source of material

5-Aminopyridine-3-carboxylic acid (0.138 g, 1 mmol) was added to a solution of 10 mL concentrated perchloric acid (70%) under room temperature and stirred for 15 min. The mixture was filtered and left to evaporate naturally. A few days later, colorless block crystals of 3-amino-5-carboxypyridin-1-ium perchlorate monohydrate were harvested, yield 78% (based on 5-aminopyridine-3-carboxylic acid [APCA]).

Experimental details

The structure was solved by direct methods with the SHELXS program. All H-atoms from C atoms and N atoms were positioned with idealized geometry and refined isotropically (Uiso(H) = 1.2Ueq(N) and Uiso(H) = 1.2Ueq(C)) using a riding model with C–H = 0.95 Åand N–H = 0.879 and 0.88 Å). The H2, H1WA and H1WB were positioned based on difference electron density peaks and refined with the distance restraints of O2–H2 = 0.84 Å, O1W–H1WA = 0.87 Åand O1W–H1WB = 0.87 Å, respectively (Uiso(H) = 1.5Ueq(O)).

Comment

5-Aminopyridine-3-carboxylic acid and its deprotonated derivatived anions are known as multi-functional ligands to build various metal (Co(II), Zn(II), Cu(II), Cd(II), Pb(II) and Y(III)) complexes [5], [6], [7], [8], [9], [10] and heterometallic complexes (Cu(II)–Ti(IV) and Cu(II)–In(III)) [11], [12], [13] with excellent applications. However, to date, the single-crystal stucture of 5-aminopyridine-3-carboxylic acid or any of its salts have not been reported.

The title compound crystalises in P1‾. The asymmetric unit of the title compound consitsts of one N-protonated 5-carboxypyridin-1-ium cation, one perchlorate anion, and one crystal water molecule. All the atoms of the 3-aminopyridine moiety are nearly co-planar, but the free carboxyl group is slightly twisted. All the bond lengths of C–C, C–N and C–O are normal, which are comparable to their analogues [14, 15]. There are two kinds of one-dimensional chains: one is constructed by the hydrogen bond N1–H1⃛O1 and the other is constructed by the hydrogen bonds O1W–H1WA⃛O5 and O1W–H1WB⃛O6. The hydrogen bonds N2–H2A⃛O4 and N2–H2A⃛O4 link the aforementioned chains to generate a three-dimensional supramolecular structure.
