Poly[aqua(dimethyl sulfoxide)(μ4-pyridine-2,5-dicarboxylato)calcium(II)]

In the polymeric title compound, [Ca(C7H3NO4)(H2O)(C2H6OS)]n, the CaII ion is coordinated in a distorted pentagonal–bipyramidal CdNO6 geometry. The crystal packing is stabilized by O—H...O hydrogen bonds and π–π stacking interactions between the aromatic rings of pyridine-2,5-dicarboxylate with centroid–centroid distances of 3.6166 (13) Å
