Abstract: In the title calcium carboxylate, {[Ca(C₉H₈NO₄)₂(H₂O)₂]·2.5H₂O}_n, prepared by the interaction of sodium 2-(pyridinium-1-yl)butanedioate with CaCl₂·6H₂O in water, adjacent Ca²⁺ ions are joined by a pair of racemic 2-(pyridinium-1-yl)butanedioate anions, forming coordination polymer strands which are further extended into a three-dimensional structure by hydrogen bonds between pendant O atoms of the carboxylate groups and water molecules.
