Abstract: In the title complex, [Cd₂(C₇H₃NO₄)₂(CH₃OH)₂(H₂O)]_n, each Cd atom has a pentagonal-bipyramidal geometry (CdNO₆). The anionic pyridine-2,6-dicarboxylate (pydc) ligands adopt a ⁵O:O,N,O':O' coordination mode. Two symmetry-related Cd^II centers are linked by a pair of carboxylate groups from two pydc ligands as well as a bridging oxygen from a water molecule located on a twofold axis, to form a dinuclear unit. These dinuclear units are further connected via carboxylate O atoms to build a one-dimensional polymeric chain. O-HO hydrogen bonds are observed within this chain.
