Abstract: In the title compound, [UO₂(C₁₅H₁₁O₂)₂(C₁₈H₁₅OP)] or [UO₂(DBM)₂(Ph₃PO)], where DBM is dibenzoyl methanate, the U^VI atom is coordinated by seven O atoms in a distorted pentagonal-bipyramidal geometry. The diphenylpropane-1,3-dionate system acts as a chelating ligand and coordinates through both of its ketonate O atoms and the triphenyl phosphine oxide ligand coordinates through the O atom. The U-O distances range from 1.759  (4) to 2.385  (4)  Å.
