4O,O':O'':O''')diyttrium(III)] trihydrate]Abstract: The title yttrium(III) coordination polymer, {[Y2(C7H3NO4)2(C2O4)(H2O)4]·3H2O}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.
