The material structure described by NaLa(SeO3)4 crystallizes in the orthorhombic Amm2 space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(5), and four equivalent O(1) atoms. La(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(4), and four equivalent O(1) atoms. Se(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted corner-sharing SeO5 trigonal bipyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one La(1), and one Se(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one La(1) and two equivalent Se(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Na(1) and two equivalent Se(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one La(1) and two equivalent Se(1) atoms. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Na(1) and two equivalent Se(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
