The structure described by LiTaNb(AgO3)2 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to one Ag(1), one Ag(2), and four equivalent O(1) atoms. Ta(1) is bonded to one O(3), one O(4), and four equivalent O(2) 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 1-2°. Nb(1) is bonded to one O(3), one O(4), and four equivalent O(1) 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 are 2°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to one Li(1), one O(3), and four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a 6-coordinate geometry to one Li(1), one O(4), and four equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded to two equivalent Ta(1), two equivalent Ag(1), and two equivalent Ag(2) atoms to form a mixture of distorted face, corner, and edge-sharing OTa2Ag4 octahedra. The corner-sharing octahedral tilt angles are 1°. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Ta(1), one Nb(1), and one Ag(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Ta(1), one Nb(1), and one Ag(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
