Source of material
All of materials are used as received. 1.68 g 5-Nitropicolinic acid (1 mmol), was added to 15 mL THF solution and stirred for 30 min without heating, then the solution was filtered and evaporated in air under room temperature. 3 days later, colorless crystals were harvested, yield 80.3% (based on 5-nitropicolinic acid).

Comment
In 1973, Fusao and Akira reported the single crystal structure of picolinic acid [5]. Thereafter, the structures of many derivatives of picolinic acid such as 2,5-pyridinedicarboxylic acid, 2,6-pyridinedicarboxylic acid [6], 2,4,6-pyridinetricarboxylic acid [7] and 2,3,5,6-pyridinetetracarboxylic acid [8] have been reported successively. Furthermore the crystal structure of picolinic acid N-oxide has been studied [9]. Some derivatives like thiol [10], trifluoromethoxyl [11], phosphonoalkyl [12], acylamino [13] or other substituent groups have although been reported [14], [15], [16]. However, there are only two nitro-substituted picolinic acids that have been studied: 4-nitropicolinic acid monohydrate and 2-carboxylic acid-4-nitropyridine-1-oxide.
The title compound 5-nitropicolinic acid crystallizes in C2/c together with one water molecule, giving the molecule formula of C6H6N2O5. All of the atoms are nearly co-planar, except the two oxygen atoms from the nitro group. The two C—O bond lengths of the carboxyl group are 1.215 and 1.305 Å, indicating that the oxygen from the longer one is protonated. Two 5-nitropicolinic acid molecules are bridged by two water molecules by two O—H⋯O hydrogen bonds to form a dimer. These dimers are linked with O—H⋯N hydrogen bonds to a two-dimensional structure. All bond lengths and angles of 5-nitropicolinic acid are normal and comparable with its analogues [17], [18], [19].
