In the crystal structure of the polymeric title compound, {[Sr(C10H6O6S2)(H2O)(4)]center dot H2O}(n), the naphthalene-1,6-disulfonate dianion uses one -SO3 unit to O,O'-chelate to an Sr-II cation and its third O atom to bind to another SrII cation. The other -SO3 unit binds to yet another Sr-II atom. The four coordinated water molecules are monodentate but one is disordered over two positions in a 1:1 ratio. The mu 3-bonding mode of the dianion generates a polymeric three-dimensional network; the network is consolidated by O-H center dot center dot center dot O hydrogen bonds. The Sr-II cation exists in an undefined eight-coordinate environment.
