Materials Data on Eu(CdSb)2 by Materials Project
EuCd2Sb2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Eu2+ is bonded to six equivalent Sb3- atoms to form EuSb6 octahedra that share corners with twelve equivalent CdSb4 tetrahedra, edges with six equivalent EuSb6 octahedra, and edges with six equivalent CdSb4 tetrahedra. All Eu–Sb bond lengths are 3.33 Å. Cd2+ is bonded to four equivalent Sb3- atoms to form CdSb4 tetrahedra that share corners with six equivalent EuSb6 octahedra, corners with six equivalent CdSb4 tetrahedra, edges with three equivalent EuSb6 octahedra, and edges with three equivalent CdSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 15–56°. There are three shorter (2.91 Å) and one longer (3.00 Å) Cd–Sb bond lengths. Sb3- is bonded to three equivalent Eu2+ and four equivalent Cd2+ atoms to form a mixture of distorted edge and corner-sharing SbEu3Cd4 pentagonal bipyramids.
