Crystal structure of tetraeuropìum dìantìmonide oxide, Еu4Sb2О

Synthesis, Structure, and Properties of Scandium Dysprosium Antimonide ScDySb

“…Table 3 and Figure 4a], which, of course, is also a distinguished feature of PbFCl (Figure 4b). The nearest neighbours of dysprosium are five Sb atoms arranged at the corners of a square pyramid, thus forming NaCl type fragments, which are also present in La 2 Sb and related structures [17,19,20]. ScDySb is a shear variant of the tI12 structure type of La 2 Sb (shear vector ½ ½ 0).…”

Syntheses, structures and properties of the pnictide oxides R2PnO2 (R=Ce, Pr; Pn=Sb, Bi)

“…There has been a lasting dispute of whether oxygen might be included in La 2 Sb type compounds (R 2 Pn) [1], which is nourished by oxygen-stuffed variants, like Eu 4 Pn 2 O [2,3], known to exist. However, it appears reasonable that the latter stuffed variants have been found only for europium and ytterbium so far, since electron precise compounds would require divalent cations.…”

New Ternary La2Sb‐Type Compounds, ScRESb (RE = La, Ce, Pr, Nd, Sm, Tb), and the Oxygen Stuffed Variant Sc4Yb4Sb4O

“…“Sr 2 Bi”10 vs. Sr 4 Bi 2 O13), just by analysing their positions within the map 15. The structural differences are reflected by an evident separation of the structure field area of the oxygen stuffed Eu 4 Sb 2 O14 from the oxygen‐free La 2 Sb‐type compounds. Especially the pair Sm 2 Sb‐Sm 4 Bi 2 O may serve as an illustrative example 15.…”

“…The resulting oxygen stuffed structures, like e.g. of Eu 4 Sb 2 O,14 are anti ‐type to K 2 NiF 4 . On the other hand, the series of reported RE 2 Pn compounds ( Pn = Sb, Bi) with tri‐valent rare‐earth metals ( RE = La, Ce, Pr, Nd, Sm) are free of oxygen 7,15–17.…”
