The structure described by LiTaNb(AgO3)2 crystallizes in the orthorhombic Pmm2 space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1), one O(1), one O(2), and two equivalent O(3) atoms. Ta(1) is bonded to one O(3), one O(4), two equivalent O(2), and two equivalent O(6) atoms to form TaO6 octahedra that share corners with two equivalent Nb(1)O6 octahedra and corners with four equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Nb(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms to form NbO6 octahedra that share corners with two equivalent Ta(1)O6 octahedra and corners with four equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted hexagonal planar geometry to two equivalent Li(1), two equivalent O(1), and two equivalent O(5) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent O(2) and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent Nb(1), and two equivalent Ag(1) atoms to form distorted corner-sharing OLiNb2Ag2 trigonal bipyramids. In the second O site, O(2) is bonded in a T-shaped geometry to one Li(1), two equivalent Ta(1), and two equivalent Ag(2) atoms. In the third O site, O(3) is bonded in a square co-planar geometry to two equivalent Li(1), one Ta(1), and one Nb(1) atom. In the fourth O site, O(4) is bonded in a linear geometry to one Ta(1) and one Nb(1) atom. In the fifth O site, O(5) is bonded in a see-saw-like geometry to two equivalent Nb(1) and two equivalent Ag(1) atoms. In the sixth O site, O(6) is bonded in a distorted linear geometry to two equivalent Ta(1) and two equivalent Ag(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
