Poly[μ(2)-aqua-aqua-μ(4)-pyridine-2,4-dicarboxyl­ato-strontium]

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-dicarboxyl­ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol­ecules in a dodeca­hedral geometry. These units are connected...

Descripción
Sumario: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-dicarboxyl­ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol­ecules in a dodeca­hedral geometry. These units are connected via the carboxyl­ate O atoms and water mol­ecules, building polymeric layers parallel to (100). In the crystal structure, non-covalent inter­actions consisting of O—H⋯O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distances = 3.862 (17) and 3.749 (17) Å] connect the various components, forming a three-dimensional structure.
