“…In combination with our previous work, 9,10 consideration that this flexibility could be used to minimise repulsion between like charges leads to the conclusion that the most favoured conformation for all three isomeric ligands would be the trans form, while a cis conformation would be unfavourable. Since the barrier to rotation about a simple C-C single bond is typically ~12 kJ mol -1 , 32 and is an energy spanned by that of hydrogen bonds, which range from ~12 kJ mol -1 for a weak interaction such as CHO, 27 to >100 kJ mol -1 for a strong interaction such as OHO, 33,34 it might be anticipated that any deviation from a trans form might be associated with such interactions.…”

“…As previously noted, 10 of 1,2-pda 2the smallest chelate ring that could be formed if both carboxylates were to bind to one metal ion would be 9-membered, a situation which is unknown in uranyl carboxylate systems except for conformationally restricted ligands, 31 (6). It is notable that the majority of diperiodic arrangements have been found within this group of neutral complexes, with only one example in an anionic complex involving the guanidinium counterion (12).…”

“…Similar (UO2)2(1,4-pda)2 rings have previously been found as subunits in different 1D or 2D assemblies. 9,10 This difference in conformation between the 1,2-pda 2ligand in 7 and 8 and the 1,3-and 1,4-pda 2ligands here is probably due to the reduced repulsion between the ring substituents in the latter. The 1,3-pda 2ligands which connect these dinuclear rings in 9 are in the trans conformation, and the chains are linear as consequence, while the 1,4-pda 2connecting ligands in 10 are also cis, which gives the chain a zigzag shape.…”

The uranium atoms are 3-c nodes and the ligands simple links, the point symbol being {6 3 } and the topological type the very common hcb (Figure 2).…”

“…We have previously reported mono-or diperiodic (denoted 1D or 2D for convenience) coordination polymers based on these ligands, the 1D chains having in some cases a tubelike shape, which incorporate diverse organic or metal-containing counterions, particularly those of the form [M(L)n] q+ , in which M = transition metal cation, L = 2,2ʹ-bipyridine (bipy) or 1,10phenanthroline (phen), n = 2 or 3, and q = 1 or 2, and Ni II or Cu II complexes with azamacrocycles, as well as Pb II cations. 9,10 Overall, all three ligands have a strong tendency to favour the formation of 1D polymers, no higher periodicity having been obtained with 1,2-pda 2-alone (not associated with 1,4-pda 2-) in particular. Both 1,3-and 1,4-pda 2were shown to give some examples of 2D networks with separate [M(L)n] q+ counterions, in which case they display topologies of the hcb type or derived from it, with 2-fold interpenetration in one case.…”

The three isomers 1,2-, 1,3-and 1,4-phenylenediacetic acids (1,2-, 1,3-and 1,4-pdaH2) have been used to synthesize 16 uranyl ion complexes under solvo-hydrothermal conditions and in the presence of various coligands and organic counterions. The two neutral and homoleptic complexes [UO2(1,2-pda)]CH3CN (1) and [UO2(1,3-pda)] (2) crystallize as diperiodic assemblies with slightly different coordination modes of the ligands, but the same sql topology. Introduction of the coordinating solvents N-methyl-2-pyrrolidone (NMP) or N,Nʹdimethylpropyleneurea (DMPU) in the uranyl coordination sphere produces the four complexes [UO2(1,2pda)(DMPU)] (3), [UO2(1,3-pda)(NMP)] (4), [UO2(1,4-pda)(NMP)] (5), and [UO2(1,4-pda)(DMPU)] (6), which are either monoperiodic (4) or diperiodic species with the fes (3 and 5) or 3,4L13 (6) topology. The presence of dimethylammonium cations is associated with the formation of ladder-like monoperiodic polymers with the 1,2 isomer in the complexes [H2NMe2]2[(UO2)2(1,2-pda)3]H2O (7) and [H2NMe2]2[(UO2)2(1,2-pda)3]3H2O (8), while a conformational change giving the 1,3 and 1,4 isomers a pincer-like geometry favors the formation of dinuclear ring subunits assembled into daisychain-like monoperiodic polymers in [H2NMe2]2[(UO2)2(1,3-pda)3]0.5H2O (9), [H2NMe2]2[(UO2)2(1,4-pda)3] (10), and the mixed-ligand species [H2NMe2]2[(UO2)2(1,2-pda)(1,4-pda)2] (11). The unique complex including guanidinium cations, [C(NH2)3]2[(UO2)2(1,2-pda)3]0.5H2OCH3CN (12), crystallizes as a diperiodic polymer with the hcb topology. Due to differences in ligand conformations, the phosphoniumcontaining complexes [PPh3Me]2[(UO2)2(1,3-pda)3] (13) and [PPh4]2[(UO2)2(1,4-pda)3] (14) contain ladder-like and daisychain-like monoperiodic polymers, respectively, while only the latter geometry is found in the mixedcation complexes [PPh3Me][H2NMe2][(UO2)2(1,4-pda)3]H2O (15) and [PPh3Me][H2NMe2][(UO2)2(1,2-pda)(1,4pda)2] (16). The influence of ligand conformation and the structure-directing effects of coligands and counterions throughout the series are discussed. The uranyl emission spectra of 14 of the complexes display the usual vibronic fine structure, the peak positions being dependent on the number of equatorial donors.

2-Carboxyphenylacetate (cpa 2À ) and 1,2-phenylenediacetate (1,2-pda 2À ) have been reacted with uranyl cations under solvohydrothermal conditions to generate six homo-or heterometallic complexes. Both [UO 2 (cpa)] (1) and [UO 2 (cpa)(phen)] (2), where phen is 1,10-phenanthroline, crystallize as monoperiodic coordination polymers. [Ni(bipy) 3 ][(UO 2 ) 2 (cpa) 3 ]•2.5H 2 O (3), is a diperiodic network with the hcb topology, in which the hexagonal cells distort to accommodate the counterions. [UO 2 (cpa) 2 Ni(R,S-Me 6 cyclam)] (4) crystallizes as a heterometallic diperiodic network in which uranyl dicarboxylate chains are assembled by bridging Ni II cations. While [dmaepH 2 ][(UO 2 ) 2 (1,2-pda) 3 ]•3H 2 O (5), where dmaep is 1,4-bis(2'-dimethylaminoethyl) piperazine, is a diperiodic hcb network, [QH] 2 [(UO 2 ) 2 (1,2pda) 3 ]•3CH 3 CN (6), where Q is quinuclidine, is the first example of a triperiodic framework in the uranyl-phenylenediacetate family, its topological type being bto. The complex involving the related ligand 1,4-phenylenediacetate (1,4-pda 2-), [QH] 2 [(UO 2 ) 2 (1,4-pda) 3 ]•2CH 3 CN ( 7), is a daisy-chain-like monoperiodic polymer. These and previously reported results are discussed in terms of ligand flexibility and ability to form large chelate rings.
