The material described by AgNbO3 crystallizes in the tetragonal P4/mbm space group. Nb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-21°. Ag(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and 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) and four equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Nb(1) and two equivalent Ag(1) atoms. is represented by the CIF file [CIF]
