A polymeric cerium(III) complex of dipicolinic acid

The title compound, catena-poly[[[diaqua(6-carboxypyridine-2-carboxylato-O,N,O′)cerium(III)]-μ-(pyridine-2,6-dicarboxylato-O,N,O′:O′′)] tetrahydrate], [Ce^III(C₇H₄NO₄)(C₇H₃NO₄)(H₂O)₂]·4H₂O, is a polymeric complex, in which Ce^III ions are linked by carboxylate O atoms of the ligands. Each Ce is coordinated by two N,O,O′-tridentate dipicolinate ligands, one of which is monoprotonated, and by two O atoms of water molecules. The coordination number of Ce is nine, because of the additional bridging Ce—O bond formed by one ligand.
