The UVI cation in the title complex, [U(C17H14BrN3O2S)O2(C4H10O)], exists within a distorted pentagonal–bipyramidal geometry, where the oxide atoms occupy the axial positions [O—U—O = 179.8 (3)°] and the pentagonal plane is defined by the N2O2 atoms of the tetradentate Schiff base ligand and the O atom of the 2-butanol molecule. In the crystal, centrosymmetric aggregates are formed via pairs of hydroxy–phenolate O—H⋯O hydrogen bonds. The azomethine C=N atoms, the ethylthiolyl group, the 2-butanol molecule and Br atom are disordered over two positions in a 0.627 (3):0.373 (3) ratio.
