Abstract: In the title compound, [Mn(C₁₄H₈N₂O₆)₂(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 [Mn-O = 2.1412 (16)-2.2262 (17) Å] from two organic ligands and four water molecules. The crystal packing is stabilized by - interactions and intermolecular O-HO and O-HN hydrogen bonds.
