Composition of saturated vapor over ytterbium bromides

The vaporization process of ytterbium di- and tribromide was studied using high-temperature mass spectrometry over the temperature range of 850 to 1300 K. It was ascertained that, at the early vaporization stages, the vapor contained molecules YbBr3, YbBr2, YbBr, Br2, Yb 2Br2, Yb2Br3, Yb2Br 4, Yb2Br5, Yb2Br6, and atoms Yb and Br. The partial pressures of all components of saturated vapor were calculated. It was found that vapor composition reflected the course of the reactions of decomposition of tribromide and disproportionation of dibromide in the condensed phase. It was concluded that vaporization of di- and tribromide was incongruent at the initial stages; vaporization of both agents acquired a congruent character with the Yb: Br = 1.0: 1.9±0.2 ratio with time.

Electron-phonon interactions in CsCdBr3=Yb3+

Pronounced electron-phonon coupling is observed for the 2F7/2?2F5/2 4f transitions of Yb3+ doped into CsCdBr3. A comparison of the Raman spectrum and the luminescence excitation sideband accompanying the 2F7/2(0)→2F5/2(2′) crystal-field transition reveals vibrational properties of the [YbBr6] coordination unit that differ markedly from those of the CsCdBr3 host. In particular, the vibronic transition associated with the totally symmetric [YbBr6] stretching mode appears as a very weak feature at 191 cm-1 in the Raman spectrum, whereas the totally symmetric [CdBr6] stretching mode of the CsCdBr3 bulk, which appears as a strong feature at 162.5 cm-1 in the Raman spectrum, is only weakly discernible in the sideband. This is direct evidence for a large contribution from [YbBr6] local modes and a small contribution from bulk modes to the vibronic intensity. The intensity of the local mode is enhanced by approximately a factor of 2 in the Raman spectrum when the laser is tuned into resonance with the 2F7/2(0)→2F5/2(2′) absorption of Yb3+, providing direct confirmation of its assignment. The observation of the first and second members of a Franck-Condon progression for both the local and the bulk totally symmetric modes indicates that a Δ process, rather than an M process, induces the vibronic intensity. Huang-Rhys factors of Slocal=0.010±0.002 and Sbulk=0.15±0.03 were determined from the data, and reflect quite different electron-phonon coupling strengths. These results suggest that multiphonon relaxation of excited electronic states proceeds by the excitation of local modes of [YbBr6] followed by energy transfer to bulk modes of the lattice, possibly through a nonlinear coupling mechanism which is discussed briefly.

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.

Synthesis and crystal structure of (NH4)3Cu4Ho2Br13. Further bromides of the (NH4)3Cu4M2Br13 Type (M = Dy-Lu, Y) and on Rb3Cu4Ho2Br13

Single crystals of (NH4)3Cu4Ho2Br13 were obtained for the first time from the reaction of CuBr with HoBr3 which was contaminated with NH4Br: cubic, space group Pn3, Z = 2, a = 1101.71(5) pm. The crystal structure may be considered as a variant of the fluorite type according to [(HoBr6)4] [(NH4)6Cu4Br)2] ≡ Ca4F8. Pure products can be prepared from the binary halides in glass ampoules at 350°C. The bromides (NH4)3Cu4M2Br13 (M = Dy-Lu, Y) and Rb3Cu4Ho2Br13 are isotypic with (NH4)3Cu4Ho2Br13.

Thermodynamics of lanthanide elements. III. Molar enthalpies of formation of Tb3+(aq), Ho3+(aq), Yb3+(aq), Yb2+(aq), TbBr3(cr), HoBr3(cr), and YbBr3(cr) at 298.15 K

Enthalpies of solution of high-purity terbium, holmium, and ytterbium metals and of the corresponding tribromides in aqueous hydrochloric acid of various molalities lead to the following standard molar enthalpies of formation ΔfHm0/(kJ * mol-1) at 298.15 K: Tb3+(aq), -(698.3+/-1.5); Ho3+(aq), -(707.2+/-2.4); Yb3+(aq), -(670.5+/-2.7); Yb2+(aq), -(530.4+/-3.3); TbBr3(cr), -(839.1+/-2.4); HoBr3(cr), -(842.1+/-2.7); YbBr3(cr), -(793.8+/-2.4).A value of -(1.06+/-0.05) V is deduced from the above results for the standard potential of the reaction: Yb3+ + 1/2H2 = Yb2+ + H+, through the use of suitable entropy values.These results are discussed and compared with previous experimental or assessed values.
