The structure described by AgNbO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Cmcm space group. Nb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 14-24°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Nb(1) and two equivalent Ag(2) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Nb(1) and two equivalent Ag(1) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Nb(1), one Ag(1), and one Ag(2) atom. is represented by the CIF card [CIF]
