Abstract: The title compound, [Nd(C₆H₃N₂O₅)₃(H₂O)₃], has a nine-coordinated system with a slightly distorted tricapped trigonal prismatic coordination geometry. The Nd^III ion is coordinated to three H₂O and by three bidentate 2,6-dinitrophenolate ligands. The Nd-O bond distances are in the range 2.311  (3)-2.730  (3)  Å. The Nd-O distances from the nitro groups are 0.2-0.3  Å longer than those from the water molecules and the phenolate groups. The coordinated NO₂ groups are almost coplanar with the benzene rings. The dihedral angles are in the range 6.72  (18)-26.65  (11)° for the coordinated NO₂ groups and 40.3  (2)-67  (1)° for the uncoordinated NO₂ groups.
