چکیده
In the title polymeric complex, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) atom is eight-coordinated by four O atoms and one N atom of four pyridine-2,4-dicarboxyl-ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol-ecules in a dodeca-hedral geometry. These units are connected via the carboxyl-ate O atoms and water mol-ecules, building polymeric layers parallel to (100). In the crystal structure, non-covalent inter-actions consisting of O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.862 (17) and 3.749 (17) Å] connect the various components, forming a three-dimensional structure.
