Intermolecular hydrogen bonding of the two independent mol­ecules of N‐3,5‐di­nitro­benzoyl‐l‐leucine

The title compound, C₁₃H₁₅N₃O₇, crystallizes as two independent mol­ecules which differ in their conformation. Intermolecular hydrogen bonding between the amide and carboxyl­ic acid groups as N—H?O=C interactions results in the formation of one‐dimensional chains with N?O distances of 2.967 (6) and 3.019 (6) Å. Neighbouring chains are linked by C=O?H—O interactions to form a two‐dimensional network, with O?O distances of 2.675 (6) and 2.778 (6) Å.
