Abstract

The U atom in the title complex, [U(C17H15N3O2S)O2(C4H10O)], exists within a distorted penta­gonal–bipyramidal geometry where the oxide O atoms occupy axial positions [O—U—O = 179.61 (18)°] and the penta­gonal plane is defined by the N2O2 atoms of the tetra­dentate Schiff base ligand and the O atom of the butan-2-ol mol­ecule. In the crystal, centrosymmetric aggregates are formed via pairs of hy­droxy–phenoxide O—H⋯O hydrogen bonds. The azomethine C=N atoms, the ethyl­thiolyl group and the butyl group of the butan-2-ol mol­ecule are disordered over two positions in a 0.668 (3):0.332 (3) ratio.
