In the title compound, disodium bis[3,6-dichloro-4,5-dihydroxy-3, 5-cyclohexadiene-1,2-dionato (2-)] dioxouranium hexahydrate, Na2[UO2(C6Cl2O4)2].6H2O, the coordination polyhedra for both uranium and sodium are pentagonal bipyramids. The uranyl anilate groups are organized in planes parallel to (301) and are connected by Na ions which also lie in these planes. The arrangement produces channels in the [010] and [001] directions which are filled with water molecules at the intersection points. A pseudo orthorhombic F cell can be found by the transformation a' = a - c, b' = b, c' = a + 3c. In this cell, the anilate planes are parallel to (100). The three water molecules, O(21), O(25) and its symmetrically equivalent O(25)', form an H2O Cluster connected by hydrogen bonding.
