(Dimethyl sulfoxide-κO)[2-({(ethylsulfanyl)[2-(2-oxidobenzylidene- κO)hydrazinylidene-κN 2]meth-yl}-iminomethyl)-phenolato- κO]dioxidouranium(VI)

Abstract

The U VI atom in the title complex, [U(C 17H 15N 3O 2S)O 2(C 2H 6OS)], exists within a distorted pentagonal-pyramidal geometry where the oxide atoms occupy axial positions [O - U - O = 177.84 (14)°] and the pentagonal plane is defined by the N 2O 2 atoms of the tetradentate Schiff base ligand and the O atom of the dimethyl sulfoxide molecule. In the crystal, centrosymmetric aggregates are formed via pairs of C - H⋯O interactions. The azomethine C=N atoms and ethylthiolyl group are disordered over two orientations in a 0.828 (3):0.172 (3) ratio.
