“…Taking a broader viewpoint, an eclectic selection from the recent literature [13,[48][49][50][51][52][53] illustrates that the solid state coordination chemistry of uranyl carboxylates continues to be an active area of research concerned with a variety of possible applications. In our own work in this area, largely focussed on anionic coordination polymers, it has been apparent that hydrogen bonding interactions can have a major influence on the form of the complexes and even upon the coordination sphere of the uranyl ion.…”

3',4, acid dianhydride has been reacted with uranyl nitrate under solvo-hydrothermal conditions and in the presence of different counterions to give three complexes of varying periodicity. [Co(en) 3 ]-[UO 2 (bptc)(HCOO)] • 2.5H 2 O (1) crystallizes as a monoperiodic coordination polymer in which the bptc 4À ligand is exclusively bound through formation of two 7-membered chelate rings. The [Co(en) 3 ] 3 + counterion is essentially a hydrogen bond donor, forming 15 hydrogen bonds with carboxylate and water oxygen atoms. In [H 2 NMe 2 ] 2 [UO 2 (bptc)] • 0.5H 2 O (2), half the ligand forms a 7-membered chelate ring, and the other half bridges two uranium atoms, resulting in the formation of a diperiodic network with hcb topology, the H 2 NMe 2 + counterions being located between the undulating sheets. [PPh 4 ] 4 [(UO 2 ) 4 (bptc) 3 ] • 6H 2 O ( 3) contains a mixture of ligands forming either four 4-membered or two 7-membered chelate rings, the latter with further bridging, which gives a triperiodic framework displaying large channels, each of which contains two rows of PPh 4 + counterions. These results are compared to those of previous studies with this ligand, and of similar studies of phthalate complexes of uranyl ion, in particular in relation to 7-membered chelate ring formation.

“…Moreover, studies of An-CPs based on uranyl or thorium ions have been explored in the last decade, mostly due to their potential applications as light emitters for sensing and photocatalysis, and the variety of novel achieved architectures [22,[40][41][42][43][44][45][46][47][48][49]. Furthermore, the rational combination of O-donor with the uranyl cation [UO 2 ] 2+ coordination modes has led to the formation of an important number of new organic-inorganic connectivity with different dimensionalities and nuclearities of uranyl-centered building units [50][51][52][53][54].…”

“…In this case, we can highlight the UNSL-1 (Universidad Nacional de San Luis) compound, [(UO 2 ) 2 (phen)(succ) 0.5 (OH) (µ 3 -O)(H 2 O)]•H 2 O, which corresponds to a 1D coordination polymer formed by tetramer units of uranyl ions, decorated by coordinated 1,10-phenanthroline molecules and connected by succinate ligands into the [-1 0 1] direction [22]. The phen plays the role of a suitable antenna molecule to store UV energy and then transfer it to the uranyl ions, yielding a bright green emission into the visible region (see Figure 6).…”

“…Moreover, the use of metallic connectors from 4f and 5f metals allows the development of materials with unique optical properties derived from their pure color emission, fine line f-transitions, and variable lifetime values depending on the desirable applications [12,15,22,23]. Additionally, the high coordination numbers and the oxophilic nature of these metallic centers [24,25] allow us to combine these ions with flexible carboxylate aliphatic ligands and build a "toolbox" to construct families of novel crystalline structures [26].…”

Three principal factors may influence the final structure of coordination polymers (CPs): (i) the nature of the ligand, (ii) the type and coordination number of the metal center, and (iii) the reaction conditions. Further, flexible carboxylate aliphatic ligands have been widely employed as building blocks for designing and synthesizing CPs, resulting in a diverse array of materials with exciting architectures, porosities, dimensionalities, and topologies as well as an increasing number of properties and applications. These ligands show different structural features, such as torsion angles, carbon backbone number, and coordination modes, which affect the desired products and so enable the generation of polymorphs or crystalline phases. Additionally, due to their large coordination numbers, using 4f and 5f metals as coordination centers combined with aliphatic ligands increases the possibility of obtaining different crystal phases. Additionally, by varying the synthetic conditions, we may control the production of a specific solid phase by understanding the thermodynamic and kinetic factors that influence the self-assembly process. This revision highlights the relationship between the structural variety of CPs based on flexible carboxylate aliphatic ligands and f-elements (lanthanide and actinides) and their outstanding luminescent properties such as solid-state emissions, sensing, and photocatalysis. In this sense, we present a structural analysis of the CPs reported with the oxalate ligand, as the one rigid ligand of the family, and other flexible dicarboxylate linkers with –CH2– spacers. Additionally, the nature of the luminescence properties of the 4f or 5f-CPs is analyzed, and finally, we present a novel set of CPs using a glutarate-derived ligand and samarium, with the formula [2,2′-bipyH][Sm(HFG)2 (2,2′-bipy) (H2O)2]•(2,2′-bipy) (α-Sm) and [2,2′-bipyH][Sm(HFG)2 (2,2′-bipy) (H2O)2] (β-Sm).

Benzene-1,2,3-tricarboxylic acid (123btcH3) was used to synthesize 7 uranyl ion complexes under hydrosolvothermal conditions, in the presence of different structure-directing agents.[Zn(phen1, phen = 1,10-phenanthroline), the only discrete species in the series, crystallizes as a binuclear, cup-shaped dimer. Both [PPh3Me][UO2(123btc)] (2) and [C(NH2)3][UO2(123btc)]0.5H2O (3) contain anionic, monoperiodic coordination polymers based on quasi-planar, binuclear (UO2)2(123btc)2 2subunits in which two oxygen atoms of each ligand are uncoordinated. Similar chains are found in [UO2(123btc)K(18C6)]H2O (4, 18C6 = 18-crown-6), the potassium cations being decorating groups bound to carboxylato and uranyl oxo donors. An analogous decorating role to monoperiodic polymers is played by UO2(DMF)2(H2O)2 2+ cations in [(UO2)3(123btc)2(DMF)2(H2O)2] (5), while bridging of chains by UO2(NMP)3 2+ cations in [(UO2)3(123btc)2(NMP)3] (6) yields a diperiodic network with V2O5 topology.[NH4][UO2(123btc)] (7), which does not contain the dimeric subunit found in the other cases, crystallizes as a diperiodic network with sql topology, the layers being associated through hydrogen bonding interactions with the ammonium counterions.
