Lanthanoid AntimonidesLn2Sb5 (Ln = Sm, Gd, Tb, Dy) and Rationalization of Chemical Bonding within the Antimony Polyanion by Combining the Zintl-Klemm Concept with Bond-Length Bond-Strength Relationships

“…Only few lanthanoid antimonides are known with an antimony content higher than 50 at-%. Eu 2 Sb 3 has been reported to be isotypic with Sr 2 Sb 3 [1]. The diantimonides LnSb 2 of the light rare earth elements (Ln = La±Tb with the exception of Eu) crystallize with a structure first determined for SmSb 2 [2,3].…”
