Crystal structure and Hirshfeld surface analysis of bis-(benzoyl-acetonato)(ethanol)dioxidouranium(VI)

A new uranium metal-organic complex salt, [U(C₁₀H₉O₂)₂O₂(C₂H₆O)], with benzoyl acetone, namely, bis-(benzoyl-acetonato)(ethanol)dioxidouranium(VI), was synthesized. The compound has monoclinic P2₁/n symmetry. The geometry of the seven-coordinate U atom is penta-gonal bipyramidal, with the uranyl oxygen atoms in apical positions. In the complex, the ligands bind to the metal through oxygen atoms. Additional weak O-H⋯O contacts between the cations and anions consolidate the three-dimensional arrangement of the structure. On the Hirshfeld surface, the largest contributions come from the short contacts such as van der Waals forces, including H⋯H, O⋯H and C⋯H. Inter-actions including C⋯C and O⋯C contacts were also observed; however, their contribution to the overall cohesion of the crystal structure is minor. A packing analysis was performed to check the strength of the crystal packing.
