In the title compound, (CH(6)N(3))[U(C(6)H(4)NO(2))(3)O(2)], the uranyl group is coordinated by two O and two N atoms from two chelating picolinate ligands, and one O atom from a third picolinate ligand. The coordination environment of the U(VI) atom (N(2)O(5)) is distorted penta-gonal-bipyramidal. In the crystal, all amino groups are involved in the formation of N-H⋯O and N-H⋯N hydrogen bonds, which link cations and anions into layers parallel to the ac plane.
