Poly[[μ-aqua-tetraaquabis(μ-2-hydroxy-4-oxocyclobut-1-ene-1,3-diolato)strontium] hemihydrate]

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-anti­prismatic geometry. The hsq anions and water mol­ecules bridge the metal i...

Descripción
Sumario: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-anti­prismatic geometry. The hsq anions and water mol­ecules bridge the metal ions into infinite sheets lying parallel to (100). The O atom of the uncoordinated water mol­ecule lies on a crystallographic twofold axis. The packing is stabilized by numerous O—H⋯O hydrogen bonds.
