Abstract

KSr2Cd2Sb3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are a spread of K–Sb bond distances ranging from 3.47–4.03 Å. There are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to six Sb3- atoms to form SrSb6 octahedra that share corners with two equivalent SrSb6 octahedra, corners with five equivalent CdSb4 tetrahedra, edges with two equivalent SrSb6 octahedra, edges with four equivalent CdSb4 tetrahedra, and a faceface with one CdSb4 tetrahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of Sr–Sb bond distances ranging from 3.40–3.58 Å. In the second Sr2+ site, Sr2+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are a spread of Sr–Sb bond distances ranging from 3.39–3.49 Å. There are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to four Sb3- atoms to form CdSb4 tetrahedra that share corners with five equivalent SrSb6 octahedra, corners with seven CdSb4 tetrahedra, and a faceface with one SrSb6 octahedra. The corner-sharing octahedra tilt angles range from 30–49°. There are a spread of Cd–Sb bond distances ranging from 2.92–3.04 Å. Inmore »« less
