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.
