The structure described by Ti2Nb2Sb3O14 crystallizes in the monoclinic C2/c space group. Ti(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(4) atoms to form a mixture of distorted corner and edge-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 43-51°. Nb(1) is bonded to one O(1), one O(7), two equivalent O(5), and two equivalent O(6) atoms to form distorted corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 39-44°. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(2) and two equivalent O(7) atoms. In the second Sb site, Sb(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. There are seven inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Ti(1) and two equivalent Sb(1) atoms. In the second O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Ti(1) atoms. In the third O site, O(4) is bonded in a 3-coordinate geometry to three equivalent Ti(1) atoms. In the fourth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms. In the fifth O site, O(6) is bonded in a 2-coordinate geometry to two equivalent Nb(1) atoms. In the sixth O site, O(7) is bonded in a distorted trigonal planar geometry to one Nb(1) and two equivalent Sb(1) atoms. In the seventh O site, O(1) is bonded in a trigonal planar geometry to one Nb(1) and two equivalent Sb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
