The first uranium–curcuminoid complex, [U(C25H23O8)2O2(CH3OH)]·C6H5CH3, features a uran­yl(VI) center coordinated by two monoanionic bidentate 4,4′-di­acetyl­curcuminato ligands and one methanol mol­ecule. The uranium atom adopts a distorted penta­gonal–bipyramidal coordination geometry, with four O atoms from the β-diketonate moieties and one O atom from the methanol ligand defining the equatorial plane, while the two uranyl O atoms occupy the axial positions.

Abstract

The first uranium–curcuminoid coordination compound has been synthesized and structurally characterized. The title complex, [U(O)2(C25H23O8)2(CH3OH)]·C6H5CH3, crystallizes in the monoclinic space group C2/c. The neutral complex comprises a uran­yl(VI) unit ({O=U=O}2+) coordinated by two monoanionic bidentate 4,4′-di­acetyl­curcuminato ligands (C25H23O8) and one methanol co-ligand, resulting in a distorted penta­gonal–bipyramidal coordination geometry. The O atoms from the β-diketonate moieties and the methanol mol­ecule form the equatorial plane, while the uranyl O atoms occupy the axial positions. In the crystal, O—H⋯O hydrogen bonds generate R22(26) ring motifs, forming zigzag chains along the a-axis direction. Additional weak C—H⋯O inter­actions further consolidate the crystal packing through inter­chain aggregation.

1. Chemical context

Curcumin [1,7-bis­(4-hy­droxy-3-meth­oxy­phen­yl)-1,6-hepta­diene-3,5-dione] is a major constituent of turmeric (Curcuma longa, Zingiberaceae) (Goel et al., 2008 ▸). Beyond its widespread use as a spice and natural food coloring, turmeric has been employed in traditional medicine to treat a broad spectrum of diseases (Goel et al., 2008 ▸; Esatbeyoglu et al., 2012 ▸). The therapeutic potential of curcumin has attracted considerable attention, and numerous studies have confirmed its anti­oxidant, anti-inflammatory (Menon et al., 2007 ▸; Dehzad et al., 2023 ▸), anti­carcinogenic (Salem et al., 2014 ▸), and anti­microbial (Dai et al., 2022 ▸) properties. From a chemical perspective, curcumin and its structural analogues are natural β-diketone ligands capable of chelating and forming stable complexes with a wide range of metal ions, including main group, transition, and rare-earth metals (Bhagat et al., 2025 ▸). In recent decades, metal-curcumin complexes have gained significant inter­est because of their diverse biological activities (Banerjee et al., 2015 ▸; Prasad et al., 2021 ▸; Bhagat et al., 2025 ▸). However, their application is often limited by extremely poor solubility in water and in most common organic solvents (Wanninger et al., 2015 ▸; Prasad et al., 2021 ▸). To overcome this limitation, structural modifications such as etherification or esterification of curcumin have been developed, leading to various derivatives and a number of structurally characterized metal complexes (Wang et al., 2014 ▸; Meza-Morales et al., 2019 ▸; Pham et al., 2020 ▸; Meza-Morales et al., 2023a ▸). Nevertheless, comprehensive structural data on curcuminoid complexes remain limited, and no actinide-curcumin complex has hitherto been structurally characterized. Herein, we report the synthesis and crystal structure of the first uranyl complex with acetyl­ated curcumin (4,4′-di­acetyl­curcumin, HL).1.

2. Structural commentary

The title compound crystallizes in the centrosymmetric monoclinic space group C2/c, with half of the mol­ecule, [U(O)2(L)2(CH3OH)]·C6H5CH3, in the asymmetric unit (Fig. 1 ▸). The complex consists of one uranyl unit (UO22+), two monodeprotonated acetyl­ated curcumin ligands {L}−, and one methanol co-ligand. The methanol mol­ecule is disordered over two symmetry-related sites with equal occupancy factors of 0.5. The uranium atom adopts a distorted penta­gonal–bipyramidal coordination geometry, with the oxido ligands occupying the axial positions. The {L}− ligands equatorially coordinate through (O,O)-chelating β-diketonate moieties, while the equatorial plane is completed by a disordered methanol ligand. The uranium atom lies 0.064 (6) Å out of the mean equatorial plane. The U=O bond length [1.772 (6) Å] and O=U=O bond angle [179.5 (3)°] fall within the expected range (Ainscough et al., 1998 ▸, Huuskonen et al., 2007 ▸, Al-Anber et al., 2011 ▸). The equatorial U1—O bond distances [U1—O1 = 2.345 (5) Å and U1—O3 = 2.351 (5) Å] are comparable to those reported for penta­gonal-bipyramidal β-diketonate uranyl complexes (Hernandez et al., 2022 ▸; Monzón González et al., 2024 ▸; Jabborova et al., 2024 ▸). The U—OMeOH bond distance [U1—O4 = 2.567 (9) Å] is longer than the U—OL bonds, indicating weaker coordination of the solvent mol­ecule compared to the chelating β-diketonate ligands. The C—C and C—O bond lengths within the chelate rings are consistent with those observed in related complexes of HL with other divalent metal ions (Meza-Morales et al., 2019 ▸; Pham et al., 2020 ▸). The partial double-bond character of these bonds reflects the expected π-electron delocalization within the β-diketonate moieties. Peripheral portions of the {L}− ligand are disordered over two positions, with refined occupancy factors of 0.5083 (1)/0.4916 (9) for one aromatic ring and its acetyl group, and 0.6046 (3)/0.3953 (7) for the acetyl group on the other ligand fragment.

3. Supra­molecular features

In the crystal structure, the complex does not form columnar packing or significant π–π stacking inter­actions. The mol­ecules are arranged as discrete units, resulting in solvent-accessible voids. Void analysis performed using OLEX2 (Dolomanov et al., 2009 ▸) indicates that the structure occupies 3588.18 Å3 (63.31%) of the unit-cell volume, leaving void space that is occupied by toluene solvent mol­ecules. These solvent mol­ecules contribute to the overall cohesion of the crystal structure.

In the crystal, O—H⋯O hydrogen bonds between the hydroxyl groups of the disordered methanol mol­ecules and the carbonyl O40 atoms of adjacent units link the mol­ecules into inversion dimers via Inline graphic(26) hydrogen-bonding motifs (Fig. 2 ▸a, Table 1 ▸). These hydrogen bonds further connect the dimers into zigzag chains extending along the a-axis direction (Fig. 2 ▸b). In addition, weak C40A—H40D⋯O20B hydrogen bonds (Fig. 3 ▸a, Table 1 ▸) link the chains into a three-dimensional supra­molecular network (Fig. 3 ▸b). A further weak inter­molecular C30—H30⋯O2 contact also contributes to the consolidation of the crystal packing.

4. Database survey

A search of the Cambridge Structural Database (CSD version 6.00, update on August 2025; Groom et al., 2016 ▸) resulted in 25 entries describing homoleptic metal complexes of curcumin and its derivatives. Among these, ten structures correspond to coordination compounds derived from 4,4′-di­acetyl­curcumin, including HOBDUA, JOCQEA, JOCQUQ, JOCRAX, PEJREE (Meza-Morales et al., 2019 ▸), KUNTUL, KUNVAT, KUNVEX, KUNVIB (Pham et al., 2020 ▸) and YIHKIN (Meza-Morales et al., 2023b ▸). A separate search for uranyl complexes based on β-diketone ligands returned 93 entries exhibiting penta­gonal–bipyramidal geometries similar to that observed in the title structure. Of these, fourteen structures have been reported within the past decade, including BUHDEP (Ma et al., 2015 ▸), NOVBUX (Kawasaki et al., 2015 ▸), VOWCUH (Vats et al., 2015 ▸), CIVVAH and CIVVEL (Carter et al., 2018 ▸), XEXZOS and XEXZUY (Kurzajewska et al., 2018 ▸), TAMTUA (Hernandez et al., 2022 ▸), EFOGOZ (Monzón González et al., 2024 ▸), GUGREJ (Jabborova et al., 2024 ▸), IMICEQ and IMICIU (Tafeenko et al., 2025 ▸), LAFKAJ and VACCAI (Clark et al., 2025 ▸).

5. Synthesis and crystallization

4,4′-Di­acetyl­curcumin (90.4 mg, 0.2 mmol) was added to 1.55 mL solution of UO2(OAc)2·2H2O (42.4 mg, 0.1 mmol) in MeOH. The color of the reaction mixture immediately changed from yellow to red–orange. After stirring the reaction mixture for 15 min, two drops of Et3N were added. Then, the temperature was increased to 313 K and kept for 1 h. During this process, a red–orange precipitate deposited, which was filtered off, washed with a small amount of MeOH and dried under vacuum. Single crystals suitable for X-ray analysis were obtained by slow evaporation of a solution of the complex in a mixture of CH2Cl2, MeOH and toluene. Yield: ∼70% (82 mg).

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The aromatic ring (C12–C17) and its acetyl group are disordered over two positions with refined occupancies of 0.5083 (1):0.4916 (9); another acetyl group is disordered in a 0.6046 (3):0.3953 (7) ratio. Aromatic C atoms of the toluene solvent were restrained to be approximately isotropic (ISOR) and planar (FLAT). Bond distances C11—C12A, C15A—O19A and those within the toluene ring were restrained using DFIX 1.4, while equivalent C—C distances in disordered acetyl groups and toluene ring were constrained using SADI. Displacement ellipsoids of disordered atom pairs including (C20A, C20B), (C39A, C39B), (C40A, C40B) and (O40A, O40B) were restrained to be similar (EADP). The Uij values of disordered atoms and aromatic carbon atoms of the toluene solvent we restrained using RIGU. Hydrogen atoms were placed in calculated positions and refined using a riding model with isotropic displacement parameters based on those of the parent atom [C—H = 0.95 Å, Uiso(H) = 1.2UeqC for CH; C—H = 0.98 Å, Uiso(H) = 1.5UeqC for CH3; O—H = 0.84 Å, Uiso(H) = 1.5UeqO for OH]. Two reflections, (131) and (243), were omitted owing to poor agreement between observed and calculated intensities.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
