Abstract

The U VI cation in the title complex, [U(C 17H 14BrN 3O 2S)O 2(C 4H 10O)], 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 N 2O 2 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 hydroxyphenolate O - H⋯O hydrogen bonds. The azomethine C=N atoms, the ethyl-thiolyl group, the 2-butanol molecule and Br atom are disordered over two positions in a 0.627 (3):0.373 (3) ratio.
