Bottom Line: The title compound, Na(3)[NpO(4)(OH)(2)]·2H(2)O, contains distorted tetra-gonal-bipyramidal centrosymmetric [NpO(4)(OH)(2)](3-) complex anions.The Np-O distances are 1.8975 (7) and 1.8891 (7) Å in the NpO(4) group and 2.3451 (7) Å to the OH group.Both Na atoms (one in a general position, the second in a special position on an inversion centre) have a distorted octahedral oxygen environment.
