Poly[tetra­aqua-μ(3)-pyridine-3,5-dicarboxyl­ato-strontium(II)]

The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium...

Sumario:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol­ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca­hedron. These binuclear units are connected via the carboxyl­ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter­actions consisting of hydrogen bonds (X—H⋯O, with X = O and C) and π–π stacking inter­actions [3.4604 (19) Å] connect the various components to form a supra­molecular structure.
