Materials Data on K9Ta10O30 by Materials Project
Abstract
K9Ta10O30 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent K sites. In the first K site, K is bonded to twelve O atoms to form KO12 cuboctahedra that share corners with eleven KO12 cuboctahedra, faces with five KO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of K–O bond distances ranging from 2.83–2.85 Å. In the second K site, K is bonded to twelve O atoms to form KO12 cuboctahedra that share corners with eleven KO12 cuboctahedra, faces with five KO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of K–O bond distances ranging from 2.83–2.85 Å. In the third K site, K is bonded to twelve O atoms to form KO12 cuboctahedra that share corners with ten KO12 cuboctahedra, faces with six KO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of K–O bond distances ranging from 2.82–2.85 Å. In the fourth K site, K is bonded to twelve O atoms to form KO12 cuboctahedra that share corners with ten KO12 cuboctahedra, faces with six KO12 cuboctahedra, and faces with eight TaO6 octahedra. There are two shorter (2.82 Å) and ten longer (2.85more »
