Source of material
All reagents are purchased from TCI Chemicals and used as received. An amount of 1.38 g of 6-aminopicolinic acid (10 mmol) was added to 10 mL concentrated hydrobromic acid (40%) and stirred for 10 min at room temperature, then filtered, left quietly, and evaporated naturally. Several days later, colorless crystals of 6-amino-2-carboxypyridin-1-ium bromide, C6H7BrN2O2 (ACPB) were obtained, yield 58% (based on 6-aminopicolinic acid).
Experimental details
The structure was solved by direct methods with the SHELXS-2018 program. All H-atoms from C and N atoms were positioned with idealized geometry and refined isotropically (U iso(H) = 1.2U eq(C) and U iso(H) = 1.2U eq(N)) using a riding model with C–H = 0.95 Å and N–H = 0.88 Å. The hydrogen atom at O1 was seen in the Fourier difference map and refined with the distance of O2–H2 = 0.84 Å (U iso(H) = 1.5U eq(O)).
Comment
Known as a multi-functional ligand, 6-aminopicolinic acid was used to construct metal complexes or metal-organic frameworks [5], [6], [7], [8], [9]. We here report the crystal structure of the bromide salt of the 6-aminopicolinic acid, ACPB. ACPB crystallizes in monoclinic system, C2/c group (no. 15). The asymmetric unit is composed of one protonated 6-aminopicolinic acid (2-amino-6-carboxypyridin-1-ium cation) and one bromide anion. The 2-amino-6-carboxypyridin-1-ium cations are linked to each other by N–H⋯Br; O–H⋯Br and N–H⋯O hydrogen bonds, respectively. All of the bond lengths of the ACPB are similar to the reported results [].
