Materials Data on LuGaCoO4 by Materials Project
Abstract
LuCoGaO4 is Aluminum carbonitride-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Lu3+ is bonded to six O2- atoms to form distorted LuO6 octahedra that share corners with three equivalent CoO5 trigonal bipyramids, corners with three equivalent GaO5 trigonal bipyramids, and edges with six equivalent LuO6 octahedra. There are three shorter (2.22 Å) and three longer (2.24 Å) Lu–O bond lengths. Co2+ is bonded to five O2- atoms to form distorted CoO5 trigonal bipyramids that share corners with three equivalent LuO6 octahedra, corners with six equivalent CoO5 trigonal bipyramids, and edges with three equivalent GaO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 63°. There are a spread of Co–O bond distances ranging from 2.00–2.38 Å. Ga3+ is bonded to five O2- atoms to form GaO5 trigonal bipyramids that share corners with three equivalent LuO6 octahedra, corners with six equivalent GaO5 trigonal bipyramids, and edges with three equivalent CoO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 62°. There are a spread of Ga–O bond distances ranging from 1.93–1.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Lu3+ and one Co2+ atom to form OLu3Comore »
