Materials Data on BaNdGaO4 by Materials Project
BaNdGaO4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.61–3.26 Å. Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.34–2.79 Å. Ga3+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ga–O bond distances ranging from 1.87–1.89 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Ba2+, two equivalent Nd3+, and one Ga3+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Ba2+, two equivalent Nd3+, and one Ga3+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Nd3+, and one Ga3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ba2+, two equivalent Nd3+, and one Ga3+ atom.
