BaEuCe2O6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. Ba(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(1), and four equivalent O(4) atoms. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. Ce(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles range from 24-36°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms. In the second O site, O(2) is bonded to two equivalent Eu(1) and two equivalent Ce(1) atoms to form distorted corner-sharing OCe2Eu2 tetrahedra. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Ba(1), two equivalent Eu(1), and two equivalent Ce(1) atoms. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Eu(1), and two equivalent Ce(1) atoms.
BaEuCe2O6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. Ba(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(1), and four equivalent O(4) atoms. Both Ba(1)-O(3) bond lengths are 3.24 Å.
