Materials Data on Ca3TiNiO6 by Materials Project
Ca3TiNiO6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.77 Å. Ti4+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share faces with two equivalent NiO6 pentagonal pyramids. All Ti–O bond lengths are 1.97 Å. Ni2+ is bonded to six equivalent O2- atoms to form distorted NiO6 pentagonal pyramids that share faces with two equivalent TiO6 octahedra. All Ni–O bond lengths are 2.18 Å. O2- is bonded in a 6-coordinate geometry to four equivalent Ca2+, one Ti4+, and one Ni2+ atom.
