Materials Data on YbGaCoO4 by Materials Project
Abstract
YbCoGaO4 is Aluminum carbonitride-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Yb3+ is bonded to six O2- atoms to form YbO6 octahedra that share corners with three equivalent CoO5 trigonal bipyramids, corners with three equivalent GaO5 trigonal bipyramids, and edges with six equivalent YbO6 octahedra. There are three shorter (2.31 Å) and three longer (2.32 Å) Yb–O bond lengths. Co2+ is bonded to five O2- atoms to form CoO5 trigonal bipyramids that share corners with three equivalent YbO6 octahedra, corners with six equivalent CoO5 trigonal bipyramids, and edges with three equivalent GaO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 60°. There are a spread of Co–O bond distances ranging from 1.75–2.03 Å. Ga3+ is bonded to five O2- atoms to form GaO5 trigonal bipyramids that share corners with three equivalent YbO6 octahedra, corners with six equivalent GaO5 trigonal bipyramids, and edges with three equivalent CoO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 60°. There are a spread of Ga–O bond distances ranging from 1.80–2.04 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Yb3+ and one Ga3+ atom to form distorted OYb3Ga tetrahedramore »
