The U(VI) cation in the title complex, [U(C(17)H(14)BrN(3)O(2)S)O(2)(C(4)H(10)O)], exists within a distorted penta-gonal-bipyramidal geometry, where the oxide atoms occupy the axial positions [O-U-O = 179.8 (3)°] and the penta-gonal plane is defined by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand and the O atom of the 2-butanol mol-ecule. In the crystal, centrosymmetric aggregates are formed via pairs of hy-droxy-phenolate O-H⋯O hydrogen bonds. The azomethine C=N atoms, the ethyl-thiolyl group, the 2-butanol mol-ecule and Br atom are disordered over two positions in a 0.627 (3):0.373 (3) ratio.
