In the title coordination polymer, {[Sr(C(4)HO(4))(2)(H(2)O)(5)]*0.5H(2)O}(n), the Sr(2+) ion is coordinated by three monodentate hydrogensquarate (hsq) anions and six aqua ligands in a distorted SrO(9) monocapped square-anti-prismatic geometry. The hsq anions and water mol-ecules bridge the metal ions into infinite sheets lying parallel to (100). The O atom of the uncoordinated water mol-ecule lies on a crystallographic twofold axis. The packing is stabilized by numerous O-H⋯O hydrogen bonds.
