DyNbO4 crystallizes in the tetragonal I4_1 space group. Dy(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Nb(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and one Nb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and one Nb(1) atom.
DyNbO4 crystallizes in the tetragonal I4_1 space group. Dy(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.37 Å) and two longer (2.39 Å) Dy(1)-O(1) bond lengths. There are two shorter (2.37 Å) and two longer (2.39 Å) Dy(1)-O(2) bond lengths. Nb(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Nb(1)-O(1) bond lengths are 1.86 Å. Both Nb(1)-O(2) bond lengths are 1.94 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and one Nb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and one Nb(1) atom.
