CeNbO4 crystallizes in the triclinic P-1 space group. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Nb(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Ce(1) and one Nb(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ce(1) and one Nb(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and two equivalent Nb(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and two equivalent Nb(1) atoms.
