Nb2SbO6 crystallizes in the monoclinic C2/c space group. Nb(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 37-54°. Sb(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Nb(1) and two equivalent Sb(1) atoms.

The corner-sharing octahedral tilt angles range from 37-54°. The Nb(1)-O(3) bond length is 2.08 Å. There is one shorter (1.88 Å) and one longer (2.07 Å) Nb(1)-O(2) bond length. There are a spread of Nb(1)-O(1) bond distances ranging from 2.05-2.22 Å. Sb(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(3) atoms. There are two shorter (2.04 Å) and two longer (2.24 Å) Sb(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms.
