Abstract: In the title compound, [Mn(C₁₄H₈N₂O₆)(H₂O)₄]_n, each 6,6'-dihydroxy-3,3'-diazenediyldibenzoate ligand acts as a carboxylate bridge, leading to the formation of polymeric chains running in the [110] direction. The Mn atom is hexacoordinated in a distorted octahedral geometry by six O atoms from two ligands and four water molecules [Mn-O = 2.1379 (16)-2.2082 (15) Å]. The crystal packing is stabilized by - interactions [centroid-to-centroid distances 3.830 (16) and 4.476 (17) Å] and intermolecular O-HO and O-HN hydrogen bonds.
