“…The formation of homologous '3:2:3' compounds for the light R and Yb will be investigated in a near future. A large number of new ternary phases adopting this structural prototype have been identified in the last decade, like the hydrogen stabilized A 5 (Sb,Bi) 3 H (A = Ca, Sr, Sm, Eu, Yb) phases [34,35], the R 5 T x (Sb,Bi) 3Àx (T = transition metal) [36,37] and R 5 XBi 2 (X = Si, Ge) [38] compounds, to cite some.…”

“…The phase diagram of the ternary system La-Ge-Bi has not yet been investigated. However, the existence and crystal structure of a ternary compound with high La content has been reported: La 5 Ge 1.2 Bi 1.8 (structure type Y 2 HfS 5 , Pearson symbol oP32, space group Pnma, a = 12.814, b = 9.604, c = 8.437 Å) [1].…”

The new ternary intermetallic compound La 2 Ge 3.03 Bi 0.81 was synthesized, and its crystal structure was determined by X-ray powder diffraction (structure type Pr 2 Ge 3.26 Bi 0.62 , Pearson symbol oS36, space group Cmcm, a = 4.2289(3), b = 31.915(2), c = 4.4379(3) Å, Z = 4). The structure is characterized by partial disorder of Bi and Ge atoms, which form a statistical mixture on one site, and by positional disorder of Ge atoms, modeled by split positions. The structure type Pr 2 Ge 3.26 Bi 0.62 is a member of the linear intergrowth structure series composed by AlB 2 -type (triple slabs of trigonal prisms) and CaF 2 -type (double slabs of "half octahedra") fragments in the ratio 3:2.

Ge-Er):Stabilization of the β-Yb5Sb3-Type Structure Through Tetrel Substitution. -The title compounds are prepared by arc-melting stoichiometric mixtures of the elements with a 5-7 wt.% excess of Bi followed by annealing at 800°C for at least two weeks. Although none of the binary bismuthides Ln5Bi3 adopt the β-Yb5Sb3-type structure the title compounds crystallize with this structure type in the space group Pnma with Z = 4 (single crystal XRD on Ce5Si0.87Bi2.13 and powder XRD for Ce5GeBi2). Despite the partial mixing of Si or Ge and Bi atoms, the structure is essentially ordered. The Ce and Pr compounds undergo magnetic transitions at low temperatures, possibly involving ferromagnetic interactions. -(BARRY, S. D.; TKACHUK, A. V.; BIE, H.; BLANCHARD, P. E. R.; MAR*, A.; J.
