Abstract: In the title compound, [Mn(C₈H₃NO₆)(C₁₀H₈N₂)(H₂O)]_n, the coordination polyhedron of the Mn^II ion is an octahedron defined by an N₂O₄ donor set. Each pair of adjacent Mn^II ions is bridged by a 5-nitrobenzene-1,3-dicarboxylate dianion to form a chiral helical chain running along a crystallographic 2₁ axis in the c direction with a long pitch of 19.04 Å. These chains are linked by O_water-HO hydrogen bonds into a layer structure.
