Sumario:In the crystal structure of the polymeric title compound, [Sr(C(10)H(6)O(6)S(2))(H(2)O)(2)](n), the naphthalene-2,7-disulfonate dianion uses one –SO(3) unit to bind to two Sr(II) cations and the other –SO(3) unit to bind to three Sr(II) cations; of the two coordinated water mol­ecules, one is monodentate to one Sr(II) cation, whereas the other bridges two Sr(II) cations. The μ(5)-bridging mode of the dianon and the μ(2)-bridging mode of the water mol­ecule generate a polymeric three-dimensional network which is consolidated by O—H⋯O hydrogen bonds. The Sr(II) cation exists in an undefined eight-coordinate environment.
