Poly[tetra­aqua­(μ8-butane-1,2,3,4-tetra­carboxyl­ato)distrontium]

In the title compound, [Sr2(C8H6O8)(H2O)4)]n, the SrII ion is coordinated by six O atoms of four symmetry-related ligands and two water mol­ecules in a distorted bicapped trigonal–prismatic environment. The butane-1,2,3,4-tetra­carboxyl­ate ligands lie on inversion centers and bridge SrII ions, forming a three-dimensional network. Within the three-dimensional structure, there are O—H⋯O hydrogen bonds involving the water mol­ecules and carboxyl­ate O atoms.
