Abstract:Reported herein are the synthesis and crystal chemistry analysis of the Zintl phase Sr21Cd4Sb18. Single crystals of this compound were grown using the Sn-flux method, and structural characterization was carried out using single-crystal X-ray diffraction. Crystal data: Monoclinic space group C2/m (No. 12, Z = 4); a = 18.2536(6) Å, b = 17.4018(5) Å, and c = 17.8979(6) Å, β = 92.024(1)°. The structure is based on edge- and corner-shared CdSb4 tetrahedra, which ultimately form octameric [Cd8Sb22] fragments, where … Show more
Polyhedral coordination in disordered Ca10MSb9 (M = Al and Cd). The new Zintl phases are intrinsic semiconductors showing ultralow thermal conductivity and candidates for the optimization of their thermoelectric performance.
