3-hydrogenglutarato-2-hydrogenglutarato-strontium(II)]Abstract: The title compound, [Sr(C5H7O4)2(H2O)2]n, crystallizes with an infinite polymeric network. The layered structure is built up from cross-linked infinite chains of one edge-sharing SrO7(H2O)2 polyhedra. One of the two crystallographically distinct ligands acts by its deprotonated group in bis-bridging-chelating mode and the second involves its two ends in bidentate and monodentate modes, respectively. The inorganic layers are pillared by methylene spacers and form empty channels. Interlayer hydrogen bonds involve mainly the protonated ends of the ligands as donors.
