EuNbO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Imma space group. Eu(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. Nb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 18-23°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Nb(1) atoms.
EuNbO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Imma space group. Eu(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. The Eu(1)-O(1) bond length is 2.51 Å. All Eu(1)-O(2) bond lengths are 2.61 Å. Nb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 18-23°. Both Nb(1)-O(1) bond lengths are 2.05 Å. All Nb(1)-O(2) bond lengths are 2.05 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Nb(1) atoms.
