The two potassium cations in the dinuclear molecule of [K2{OC(C14H13ON2)O}2{OC(C14H13ON2)OH}4(H2O)2] are connected through a double bridge involving two centrosymmetrically related ethyl-4-(phenylazophenol)benzoate ligands. Each cation is also bound to a further non-bridging ligand, one ethyl-4-(phenylazophenolate)benzoate anion and a water molecule, leading to a distorted fivefold coordination. The two uncharged ligands are almost planar, whereas in the anionic ligand the aromatic systems display a dihedral angle of 21.14 (11)°. A supramolecular network formed by hydrogen-bonding interactions between phenolate anions, phenol groups and water molecules connects the dimeric species along [001]. Hirshfeld surface calculations revealed the following contributions related to intermolecular interactions: C...H (24.4%), O...H (13.2%) and N...H (7.4%). The azo fragment is disordered over two sets of sites [occupancy ratio 0.824 (15):0.176 (5)].
