AgNbO3 crystallizes in the orthorhombic Cmmm space group. Nb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form a mixture of edge and corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Nb(1) atoms. In the second O site, O(2) is bonded to two equivalent Nb(1), one Ag(1), and one Ag(2) atom to form a mixture of edge and corner-sharing ONb2Ag2 tetrahedra.
