Materials Data on KZn4(SbO4)3 by Materials Project
Abstract
KZn4Sb3O12 crystallizes in the trigonal R3 space group. The structure is three-dimensional. K1+ is bonded to twelve O2- atoms to form distorted KO12 cuboctahedra that share corners with nine equivalent SbO6 octahedra, edges with six equivalent ZnO4 tetrahedra, faces with two equivalent ZnO6 octahedra, and faces with three equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 39–44°. There are a spread of K–O bond distances ranging from 2.74–3.22 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share a cornercorner with one ZnO6 octahedra, corners with five equivalent SbO6 octahedra, corners with two equivalent ZnO4 tetrahedra, and edges with two equivalent KO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 52–61°. There are a spread of Zn–O bond distances ranging from 1.97–2.00 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with three equivalent SbO6 octahedra, corners with three equivalent ZnO4 tetrahedra, edges with three equivalent SbO6 octahedra, and faces with two equivalent KO12 cuboctahedra. The corner-sharing octahedral tilt angles are 20°. There are three shorter (2.08 Å) and three longer (2.21more »
