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

Abstract

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.

“…Pyridine-2,5-dicarboxylic acid (2,5-pydcH 2 ) can coordinate to metal centers (Pasdar et al, 2011) or form hydrogen-bonded networks (Zeng et al, 2005). Our research group has been focused on synthesis of proton transfer compounds containing different proton donor and acceptor groups (Eshtiagh-Hosseini et al, 2010a;Eshtiagh-Hosseini et al, 2010b;Aghabozorg et al, 2008Aghabozorg et al, , 2011.…”
