In the title compound, [Ni(C20H13O5P)(C12H10N2)(H2O)]n, the NiII cation is coordinated by three O atoms from two 5-(diphenylphosphinoyl)isophthalate anions, two N atoms from two 1,2-bis(pyridin-4-yl)ethene ligands and one water molecule in a distorted octahedral geometry. Both 1,2-bis(pyridin-4-yl)ethene and 5-(diphenylphosphinoyl)isophthalate bridge the NiII cations to form polymeric layers parallel to (001). In the crystal, O—H⋯O hydrogen bonding links layers into a three-dimensional supramolecular structure.
