Abstract: In the title compound, [UO₂(C₁₅H₉O₂)₂(C₁₇H₁₈O)] or [UO₂(DBM)₂(DBA)], where DBM is dibenzoyl methanate and DBA is dibenzylacetone, 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, while the DBA ligand coordinates through the O atom. The average U-O distances for U-O(uranyl) [1.742 (2) Å], U-O(diketonate) [2.349 (2) Å] and U-O(DBA) [2.406 (2) Å] are within normal ranges. The DBA molecule retains its trans-trans geometry in the structure.
