Poly[bis[aquaneodymium(III)]‐μ2‐oxalato‐di‐μ4‐succinato]

In the title compound, [Nd₂(C₄H₄O₄)₂(C₂O₄)(H₂O)₂]_n, the flexible succinate anion assumes the gauche conformation and bridges the nine‐coordinate Nd atoms to generate two‐dimensional layers parallel to (010). The coordination polymer layers are linked into a three‐dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion.
