The crystal structure described by SbNbO4 crystallizes in the orthorhombic Pnna space group. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 39°. Sb(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Nb(1) and two equivalent Sb(1) atoms. is represented by the CIF card [CIF]
