Single crystal studies of the europium pnictide EuZn2Sb2

Ternary CaCu4P2-type pnictides AAg4Pn2 (A=Sr, Eu; Pn=As, Sb)

“…However, CaAl 2 Si 2 -type compounds have the potential to exhibit physical properties that are just as interesting as the more heavily investigated ThCr 2 Si 2 -type compounds. Within the ternary pnictide systems A-Zn-Pn, the antimonides AZn 2 Sb 2 (A ¼alkaline-earth metals such as Sr or divalent rare-earth metals such as Eu) have been recently identified as promising thermoelectric materials [2][3][4][5][6][7][8][9]. Furthermore, CaAl 2 Si 2 -type phases serve as an attractive platform to design other structures.…”

Synthesis and properties of CaCd2Sb2 and EuCd2Sb2

“…The compounds with a nominal composition of AM 2 X 2 (A is alkaline-earth or rare-earth element, M is a transition-metal or a main group element, and X comes from group 15, 14, or more rarely 13) favorably crystallize in ThCr 2 Si 2 type structure (I4/mmm) [11,12], while the above mentioned antimonide analogues crystallized in the trigonal CaAl 2 Si 2 type ðP3mÞ, which is critically tied to the number of valence electrons per formula unit with 16 electrons [13][14][15][16][17][18][19][20][21][22]. Such an electron count can only be achieved for d 0 , d 5 and d 10 metals for antimonide analogues, such as Mg, Mn, Zn, Cd in Refs.…”
