[S-Allyl-4-(4-hy-droxy-2-oxidobenzyl-idene-κO)-1-(2-oxidobenzyl-idene-κO)isothio-semicarbazidato-κN,N](ethanol-κO)dioxido-uranium(VI) ethanol monosolvate.

In the title compound, [U(C(18)H(15)N(3)O(3)S)O(2)(C(2)H(5)OH)]·C(2)H(5)OH, the U(VI) ion is in a distorted penta-gonal-bipyramidal coordination geometry, with two oxide O atoms in axial sites. Two N and two O atoms of the tetra-dentate ligand and an O atom of an ethanol ligand form the equatorial plane. The dihedral angle between the mean planes of the two benzene rings is 34.8†(3)°. In the crystal, relatively strong O-H⋯O hydrogen bonds connect the complex and ethanol solvent mol-ecules into alternating centrosymmetric R(2) (2)(8) and R(4) (4)(16) ring motifs, forming chains along [100]. Weak inter-molecular C-H⋯O hydrogen bonds are also present.
