SbTaO4 crystallizes in the orthorhombic Pnna space group. Ta(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing TaO6 octahedra. Sb(1) is bonded in a 6-coordinate geometry to two 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 3-coordinate geometry to two equivalent Ta(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ta(1) and two equivalent Sb(1) atoms.
SbTaO4 crystallizes in the orthorhombic Pnna space group. Ta(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing TaO6 octahedra. Both Ta(1)-O(2) bond lengths are 1.98 Å. There are two shorter (1.98 Å) and two longer (2.11 Å) Ta(1)-O(1) bond lengths. Sb(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Sb(1)-O(1) bond lengths are 2.43 Å. There are two shorter (2.05 Å) and two longer (2.60 Å) Sb(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ta(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ta(1) and two equivalent Sb(1) atoms.
