Abstract: The title complex, [Nd(C₈H₅Cl₂O₃)₃(H₂O)]_n, is a neodymium polymer based on the flexible 2,4-dichlorophenoxyacetate ligand. The Nd^II center is coordinated by eight O atoms from five 2,4-dichlorophenoxyacetate ligands and one water molecule, and displays a distorted tricapped trigonal-prismatic geometry. The Nd centers are linked by the (2,4-dichlorophenoxy)acetate ligands via two bridging carboxylate O atoms, with an NdNd distance of 4.172 (3) Å, forming chains along the c axis. The chains are assembled into ruffled layers via - stacking interactions; the centroid-centroid and offset distances between phenyl groups [at (-1 + x, y, -1 + z)] are 3.719 (2) and 0.060 (2) Å, respectively, indicating a normal - stacking interaction.
