Phase equilibria and crystal structures in the system Eu–Pd–B

Valence fluctuations of europium in the boride Eu4Pd29+xB8

“…The refined composition Eu 2 Pd 14.9 B 4 is in good agreement with that from the WDXS analysis. The obtained structural model is the same as reported for Eu 4 Pd 29 B 8 [35] and Eu 2 Pd 14.9 B 4.9 [28,29] with the only difference that the occupation of the Pd2 site is 44(1)% in our case, instead of 25(1)% observed in Eu 4 Pd 29 B 8 . No boron in 8e could be found, as it is reported for Eu 2 Pd 14.9 B 4.9 .…”

“…However, the crystal structure of this compound remains unknown. Crystal structure and physical properties of a boride with the composition Eu 2 Pd 15 B 5 are reported in [28,29], respectively. Magnetic susceptibility measurement showed that the Eu ion is in an IV state, and the ICF model was used to understand its dynamics.…”

Cage compound Sc5Pt24B12: a Pt-stuffed variant of filled skutterudite structure. Electronic and structural properties

“…21,53,69,70 A series of split and defect variants of Yb 3 Rh 4 Sn 13 type form as a result of distinct population parameters of atomic positions (space group Pm 3̄ n ). 21 While the two latter structure types are extensively represented in ternary systems containing various p-block elements as a third component, 21,46,55,71–73 the anti-perovskite type compounds (and their derivative structure of CePt 3 B-type 74 ) tend to form primarily in boride systems 74–80 ( e.g. , only few silicon-containing ternaries exhibiting this structural arrangement were reported so far 81–85 ).…”

“…(and their derivative structure of CePt 3 B-type 74 ) tend to form primarily in boride systems [74][75][76][77][78][79][80] (e.g., only few silicon-containing ternaries exhibiting this structural arrangement were reported so far [81][82][83][84][85] ). On the other hand, among a large number of boride compounds, only few series of transition metal ternaries adopt the structure types relevant to other p-block elements, e.g.…”
