EuGaO3 crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Ga(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form corner-sharing GaO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent Ga(1) atoms. In the second O site, O(1) is bonded to three equivalent Eu(1) and one Ga(1) atom to form a mixture of edge and corner-sharing OEu3Ga tetrahedra.
EuGaO3 crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All Eu(1)-O(1) bond lengths are 2.35 Å. Ga(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form corner-sharing GaO5 trigonal bipyramids. Both Ga(1)-O(1) bond lengths are 1.88 Å. All Ga(1)-O(2) bond lengths are 2.12 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent Ga(1) atoms. In the second O site, O(1) is bonded to three equivalent Eu(1) and one Ga(1) atom to form a mixture of edge and corner-sharing OEu3Ga tetrahedra.
