In the title picryl-substituted ester, C13H6BrN3O8, the mean plane of the central ester C–O–C(=O)–C fragment (r.m.s. deviation= 0.0186 Å) is rotated by 84.73 (7)° and 19.92 (12)° to the picryl and phenyl rings, respectively. In the crystal, the mol­ecules are linked by C—H...O inter­actions, forming centrosymmetric dimers enclosing R22(10) and R22(22) ring motifs along [001] and further helical chains of dimers enclosing R22(10) ring motifs along [010].
