Exploratory Work in the Quaternary System of Ca⁻Eu⁻Cd⁻Sb: Synthesis, Crystal, and Electronic Structures of New Zintl Solid Solutions.

ABSTRACT: Investigation of the quaternary system, Ca⁻Eu⁻Cd⁻Sb, led to a discovery of the new solid solutions, Ca_1-xEu_xCd₂Sb₂, with the CaAl₂Si₂ structure type (x ≈ 0.3⁻0.9, hP5, P 3 ¯ m1, a = 4.6632(5)⁻4.6934(3) Å, c = 7.630(1)⁻7.7062(7) Å), Ca_2-xEu_xCdSb₂ with the Yb₂CdSb₂ type (x ≈ 0.6, oS20, Cmc2₁, a = 4.646(2) Å, b = 17.733(7) Å, c = 7.283(3) Å), and Eu_11-xCa_xCd₆Sb₁₂ with the Sr₁₁Cd₆Sb₁₂ type (x ≈ 1, mS58, C2/m, a = 32.407(4) Å, b = 4.7248(5) Å, c = 12.377(1) Å, β = 109.96(1)°).
