Materials Data on KBa3(BiO3)4 by Materials Project
Abstract
KBa3(BiO3)4 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. K1+ is bonded to twelve O2- atoms to form distorted KO12 cuboctahedra that share corners with four equivalent KO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, and faces with eight BiO6 octahedra. There are a spread of K–O bond distances ranging from 2.88–3.37 Å. There are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.87–3.38 Å. In the second Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.85–3.40 Å. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, faces with four equivalent KO12 cuboctahedra, and faces with eight BiO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.86–3.39 Å. There are two inequivalent Bi+4.25+ sites. In the first Bi+4.25+ site, Bi+4.25+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with six BiO6 octahedra, faces with two equivalentmore »
