✦ Synopsis

The title yttrium(III) coordination polymer, {[Y~2~(C~7~H~3~NO~4~)~2~(C~2~O~4~)(H~2~O)~4~]·3H~2~O}~n~, has a pyridine-3,4-dicarboxylate (PDC) and oxalate (ox) bridged layer-type structure. The central yttrium ion exhibits a distorted dodecahedral configuration, coordinated by eight O atoms from three PDC ligands, one ox ligand and two uncoordinated water molecules. The ox ligand lies on a center of inversion.
