LaNbO4 crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted edge-sharing NbO6 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Nb(1) atom.
LaNbO4 crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.49 Å) and two longer (2.55 Å) La(1)-O(1) bond lengths. There are two shorter (2.46 Å) and two longer (2.52 Å) La(1)-O(2) bond lengths. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted edge-sharing NbO6 tetrahedra. Both Nb(1)-O(2) bond lengths are 1.87 Å. There are two shorter (1.94 Å) and two longer (2.54 Å) Nb(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Nb(1) atom.
