“…The crystal solved as 7 (see Figure 7) in a 3OS arrangement for the halides, 9 MeOH solvent molecules bound to the La metal center, and an additional MeOH located in the unit cell lattice. The coordination around the metal center is in direct contrast with the literature reported ROH derivatives [LnI 3 (Pr i OH) 4 ][39] (Ln = Ce, La) and [LuI 2 (Pr i OH) 4 ](I)[38]. None of these compounds are reasonable models and as a result the La-ROH distances of 7 (av 2.55 Å) were found to be longer in comparison: 2.238 – 2.271 Å (Lu),[38] 2.492 – 2.524 Å (La) , and 2.478 – 2.496Å (Ce).…”

“…The two iodide ligands and two distal nitrogen atoms (N d ) of the two terpy ligands [N(3) and N(4)] occupy the opposite corners of the first square base, respectively, whereas the second basis is defined by the two central nitrogen atoms (N c ) [N(2) and N(5)] and the other two distal nitrogen atoms of the terdentate molecule [N(1) and N(6)], which are mutually trans .

The addition of 2,2Ј:6Ј,2ЈЈ-terpyridine (terpy) to MI 3 (M = Ce, Nd, U) in anhydrous pyridine led to the quantitative formation of the bis-terpy complexes [MI 2 (terpy) 2 ]I [M = Ce (1) and Nd (2)] and [MI 2 (terpy) 2 L]I [M = U and L = pyridine (3); M = Ce and L = H 2 O ( 4)]. Conductometry measurements indicated that these complexes are 1:1 electrolytes in pyridine solution. 1 H NMR competition experiments showed that the terdentate ligand has a better affinity for U III than for Ce III or Nd III .

New Family of Cerium Halide Based Materials: CeX₃·ROH Compounds Containing Planes, Chains, and Tetradecanuclear Rings

et al. 2012

Six members of a new family of cerium-halide-based materials with promising scintillation behavior have been synthesized in single crystal form, and their crystal structures were determined. Specifically, these new compounds are [(CeCl(3))(7)(BuOH)(16)(H(2)O)(2)]·(BuOH)(2) (1), (CeBr(3))(14)(BuOH)(36) (2), [(CeCl(3))(7)(1-PrOH)(16)(H(2)O)(2)]·(1-PrOH)(2) (3), [(CeBr(3))(7)(1-PrOH)(18)]·(1-PrOH)(2) (4), [(CeCl(3))(6)(iBuOH)(15)]·(iBuOH)(2) (5), and CeCl(3)(sec-BuOH)(2)(H(2)O) (6). Additionally, the scintillation ability of compound 1 was established. The structures of these cerium-halide-based materials consist of catenated tetradecanuclear rings that arrange themselves into three distinct structural motifs which contain the largest lanthanide-based ring structures reported to date; the different motifs are obtained by involving specific alcohols during synthesis. Specifically, n-butanol and n-propanol lead to 1-D chains of tetradecanuclear rings, and iso-butanol leads to 2-D parquet-patterned sheets of rectangular tetradecanuclear rings, while sec-butanol results in a zigzag 1-D chain structure. One of the compounds, [(CeCl(3))(6)(iBuOH)(15)]·(iBuOH)(2), has been shown to scintillate with a light yield of up to 1920 photons/MeV, and due to the presence of protons, it should be capable of detecting high energy neutrons without the necessity of prior thermalization. Furthermore, it also appears to be the first cerium-based compound that scintillates in spite of the fact that water coordinates to two of the Ce(III) centers within the structure.
