LaONO3 crystallizes in the orthorhombic Pmmn space group. La(1) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(3) atoms. N(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one La(1) and one N(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OLa4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent La(1) and one N(1) atom.
LaONO3 crystallizes in the orthorhombic Pmmn space group. La(1) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(3) atoms. The La(1)-O(1) bond length is 2.79 Å. There are two shorter (2.38 Å) and two longer (2.52 Å) La(1)-O(2) bond lengths. All La(1)-O(3) bond lengths are 2.71 Å. N(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(3) atoms. The N(1)-O(1) bond length is 1.23 Å. Both N(1)-O(3) bond lengths are 1.27 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one La(1) and one N(1) atom.
