ABSTRACT: The structure of the binuclear title complex, [U(2)(C(5)H(3)N(2)O(2))(4)O(4)(H(2)O)(2)]·2H(2)O, is composed of centrosymmetric dimers in which each UO(2) (2+) ion is coordinated by two ligand mol-ecules. One donates its N,O-bonding group and the other donates both carboxyl-ate O atoms. Each of the latter bridges adjacent uranyl ions. The coordination environment of the metal center is a distorted penta-gonal bipyramid. The dimers are inter-connected by O-H⋯O hydrogen bonds between coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms. An intra-molecular O-H⋯N inter-action is also present.
