Bis(2-benzoyl-1-phenylethenolato-κ2 O,O′)(ethanol-κO)dioxidouranium(VI)

In the title compound, [U(C15H11O2)2O2(C2H6O)], the UVI atom has a pentagonal–bipyramidal coordination geometry. The two so-called ‘-yl’ O atoms occupy the axial positions whereas four O atoms from the two chelating dibenzoylmethanate ligands and the O atom from the ethanol molecule are situated in the equatorial plane. Intermolecular hydrogen bonds between one of the ‘-yl’ O atoms and the ethanol OH group assemble molecules into a centrosymmetric dimer.
