1 Source of materials

6-Amino-pyridinium-2-carboxylate was obtained as the following: 0.1381 g 6-aminopyridine-2-carboxylic acid (0.1 mmol), 0.1572 g 2-quinolinecarboxaldehyde (1.0 mmol), 0.2165 g lanthanum(III) nitrate hexahydrate (0.50 mmol), and 0.040 g NaOH (1.0 mmol) were together added to the solution of 15 mL ethanol-water (v:v = 2:1) with stirring. Then the mixture was stirred for 3 h at 75 °C and then cooled to room temperature. The colourless block crystals of the title compound were received in 6 days.

2 Experimental details

The hydrogen atoms were positioned geometrically (C–H = 0.93 Å, N–H = 0.82–0.86 Å). Their Uiso values were set to 1.2Ueq or 1.5Ueq of the parent atoms.

3 Comment

The study of rare earth metal complexes has always been one of the research fields of coordination chemistry for their excellent potential applications in catalysis, 5 , 6 fluorescent probe, 7 antitumor activity. 8 We have synthesized and structural characterized some rare earth metal complexes. 9 , 10 , 11 To further enrich the structure of the rare earth complex, we proposed to synthesize a new complex from 6-aminopyridine-2-carboxylic acid, 2-quinolinecarboxaldehyde and lanthanum(III) nitrate hexahydrate. However, unlike our expected results, 6-aminopyridine-2-carboxylic acid and 2-quinolinecarboxaldehyde did not react to form the Schiff base ligand, and the lanthanum(III) ion were not involved in coordination. Only a single crystal of 6-amino-pyridinium-2-carboxylate was obtained. The molecular structure of 6-amino-pyridinium-2-carboxylate is shown in Figure. Single-crystal structural analysis shows that the 6-amino-pyridinium-2-carboxylate crystallizes in the monoclinic system with the P21/n (no. 14) space group. The bond lengths of C–O and C–N are in the range of 1.239(3) Å–1.257(3) Å and 1.325(3) Å–1.362(3) Å, 12 respectively. In the crystal structure, it forms a 1D chained structure via strong intermolecular N–H⋯O hydrogen bonds. The 1D chains further form a two-dimensional layered structure via π stacking interactions of pyridinium rings.
