Planar B4 rhomboids: The rare earth boride halides RE4X5B4

The new compounds RE4X5B4 (RE = La, Ce, Pr, Gd and X = Br, I) and RE4I5B2C (RE = La, Ce) are prepared via the reaction of RE metal, REX3 and B, or B and C at temperatures 1670 ≥ T ≥ 1270 K in welded tantalum ampoules. Chains of interconnected B4 rhomboids are the characteristic features of the crystal structures. According to band structure calculations, the compounds are one-dimensional metals which undergo a gradual metal-to-semiconductor transition at low temperature as experimentally indicated by the steep inrease of electrical resistivity.

The enthalpies of formation of praseodymium halides PrCl3, PrBr3, and PrI3 in the crystalline state and aqueous solution

The enthalpies of solution of praseodymium tribromide and triiodide in water were measured at 298.15 K in a hermetic isothermic-shell swinging calorimeter. The data obtained and the Δf H° (Pr 3+, sln, ∞H2O, 298 K) value found earlier were used to calculate the enthalpies of formation of three praseodymium halides (PrCl3, PrBr3, and PrI3) in the crystalline state and aqueous solution.

Thermodynamic and transport properties of the PrBr3-RbBr binary system

Phase equilibrium in the PrBr3RbBr binary system was established by differential scanning calorimetry (DSC). This system, investigated for the first time, includes Rb3PrBr6, Rb2PrBr 5 and RbPr2Br7 compounds, and three eutectics located at molar fraction of PrBr3 (x = 0.136; 865 K), (x = 0.488; 765 K) and (x = 0.679; 834 K), respectively. Rb3PrBr6 undergoes a solidsolid phase transition at 704K and melts congruently at 995 K. Rb2PrBr5 melts incongruently at 803K and finally RbPr2Br7 melts congruently at 852 K. The electrical conductivity of PrBr3RbBr liquid mixtures was measured over an extended temperature range down to temperatures below solidification and over the whole composition range. Results obtained are discussed in terms of possible complex formation.

Structural characterization of methanol substituted lanthanum halides

The first study into the alcohol solvation of lanthanum halide [LaX3] derivatives as a means to lower the processing temperature for the production of the LaBr3 scintillators was undertaken using methanol (MeOH). Initially the de-hydration of {[La(μ-Br)(H2O)7](Br)2}2 (1) was investigated through the simple room temperature dissolution of 1 in MeOH. The mixed solvate monomeric [La(H2O)7(MeOH)2](Br)3 (2) compound was isolated where the La metal center retains its original 9-coordination through the binding of two additional MeOH solvents but necessitates the transfer of the innersphere Br to the outersphere. In an attempt to in situ dry the reaction mixture of 1 in MeOH over CaH2, crystals of [Ca(MeOH)6](Br)2 (3) were isolated. Compound 1 dissolved in MeOH at reflux temperatures led to the isolation of an unusual arrangement identified as the salt derivative {[LaBr2.75·5.25(MeOH)]+0.25 [LaBr3.25·4.75(MeOH)]-0.25} (4). The fully substituted species was ultimately isolated through the dissolution of dried LaBr3 in MeOH forming the 8-coordinated [LaBr3(MeOH)5] (5) complex. It was determined that the concentration of the crystallization solution directed the structure isolated (4 concentrated; 5 dilute) The other LaX3 derivatives were isolated as [(MeOH)4(Cl)2La(μ-Cl)]2 (6) and [La(MeOH)9](I)3·MeOH (7). Beryllium Dome XRD analysis indicated that the bulk material for 5 appear to have multiple solvated species, 6 is consistent with the single crystal, and 7 was too broad to elucidate structural aspects. Multinuclear NMR (139La) indicated that these compounds do not retain their structure in MeOD. TGA/DTA data revealed that the de-solvation temperatures of the MeOH derivatives 4-6 were slightly higher in comparison to their hydrated counterparts.
