The X-ray structure of 2-amino-4-nitropyridine was determined at room temperature. The crystal belongs to the P21/c space group of the monoclinic system (Z= 4, a= 6.7290 (10), b= 10.946 (2), c= 9.060 (2) Å, β= 100.03 (3) deg) and is built of layers parallel to the (102) crystallographic plane. The molecules in the layer are joined into centrosymmetric dimers by two N–H⋯ N hydrogen bonds (N⋯ N distance= 3.011 (3) Å), which form rings of Ci ...
