“…5 Moreover, a rich portfolio of ligands with a strong tendency to coordinate, such as carboxylates and phosphonates, to [UO 2 ] 2+ further diversifies both the building units and the resulting topologies. [6][7][8][9][10][11][12][13][14][15] The cumulative effects of speciation and ligand contribution ultimately make the synthesis of materials with a desired topologies rather challenging.…”

The synthesis and crystal structures of eight compounds containing the anionic uranyl isothiocyanate tecton [UO 2 (NCS) 4 (H 2 O)] 2− , charge balanced by substituted pyridinium cations (4XpyH: X = Cl, Br, I, SCN, CH 3 , NH 2 , N(CH 3 ) 2 ) are reported. Hydrogen bonding interactions between coordinated water molecules and the non-coordinated sulfur atoms (O-H 2 ⋯S) of the adjoining tectons facilitate the formation of infinite 'pseudo' chains of inorganic tectons. The substituted pyridinium cations were paired with these fixed uranyl isothiocyanate tectons due to their ability to sustain multiple intermolecular interactions with the sulfur atoms of the uranyl tectons, thus promoting assembly. The variation of the substituent group bound to the organic cations allowed for the resulting non-covalent interactions to be systematically assessed in order to determine their relative effects upon packing. Additionally, respective acceptor-donor pairings as well as the relative strengths of the halogen, pseudohalogen [C-X⋯A (X = Cl, Br, I, SCN and A = O, S)] and hydrogen bonding [R-H⋯A (R = N, C and A = O, S, π)] interactions were investigated. The acceptor-donor relationships emulated hard-soft pairings and consequently increased in strength as a function of this trend.

“…These chains are connected by Mn-centered moieties through Mn O P and Mn O U interactions, leading to the 3D heterometallic uranyl phosphonoacetate (Fig. 32b) [ [70][71][72] owing to the high-symmetry and porosity. The structure crystallizes in the highly symmetrical cubic space group Im-3, which is exceedingly rare for uranyl compounds.…”

“…The cadmium uranyl phosphonoacetate Cd 3 (UO 2 ) 6 (H 2 O) 13 (PPA) 6 ·6H 2 O [71,72] is also remarkable in that it crystallizes in the rhombohedral space group R-3 and features a nano-sized channel along the c-axis, which is uncommon in uranyl phosphonate compounds (Fig. 34).…”

“…The crystallization of molecular species from aqueous solution using carboxylate ligand can help to fill this lack of information, especially if the selected organic linker occurs naturally. Regarding the literature, the association of uranyl and heterometal (M) such as a divalent transition metal or rare earth is particularly studied with heterofunctional linker molecules (carboxyphosphinates, phosphonate–carboxylates, − pyridine-carboxylates − ) or the addition of N-donor molecules. − The isolation of bimetallic UO 2 2+ –M coordination polymers with carboxylate ligands is also reported (M = Ni 2+ , ,− Co 2+ , , Cu 2+ , − Zn 2+ , ,, Ln 3+ ,− ).…”

Five new heterometallic UO-Co coordination polymers have been obtained by hydrothermal reactions of uranyl nitrate and metallic cobalt with aromatic polycarboxylic acids. Single-crystal X-ray diffraction reveals the formation of four 3D frameworks with the mellitate (noted mel) ligand and one 2D network with the isophthalate (noted iso) ligand. The compounds [(UO(HO))Co(HO)(mel)]·4HO (1), [UOCo(HO)(Hmel)]·2HO (2), and [(UO(HO))Co(HO)(mel)] (4) consist of 3D frameworks built up from the connection of mellitate ligands and mononuclear metallic centers. These three compounds exhibit two types of geometry for the uranyl cation: pentagonal bipyramidal environment for 1 and 4, and hexagonal bipyramidal environment for 2. Using the mellitate ligand, the uranyl dinuclear unit is isolated in the compound [(UO)(OH)(Co(HO))(mel)]·2HO (3). Due to their 2D framework and the presence of uncoordinated cobalt(II) cations, the compound [(UO)(iso)][Co(HO)]·3(HO) (5) is drastically different than the previous one. The thermal behavior of compounds 1, 2, and 3 has been studied by thermogravimetric analysis, X-ray thermodiffraction, and in situ infrared. By heating, the dehydration of compounds 1 and 2 promotes two structural transitions (1 → 1' and 2 → 2'). The crystal structures of [(UO(HO))Co(HO)(mel)] (1') and [(UO)Co(Hmel)] (2') were determined by single-crystal X-ray diffraction; each of them presents a heterometallic interaction between uranyl bond and the Co(II) center. Due to the rarely reported coordination environment for the cobalt center in compound 2' (square pyramidal configuration), the magnetic properties and EPR characterizations of the compounds 2 and 2' were also investigated.
