Sr2CoSbO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Sb(1), four equivalent O(1), and four equivalent O(2) atoms. Co(1) is bonded in an octahedral geometry to two equivalent O(1) and four equivalent O(2) atoms. Sb(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one Co(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1), one Co(1), and one Sb(1) atom.
Sr2CoSbO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Sb(1), four equivalent O(1), and four equivalent O(2) atoms. The Sr(1)-Sb(1) bond length is 3.64 Å. There are two shorter (2.61 Å) and two longer (3.25 Å) Sr(1)-O(1) bond lengths. All Sr(1)-O(2) bond lengths are 2.64 Å. Co(1) is bonded in an octahedral geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Co(1)-O(1) bond lengths are 1.99 Å. All Co(1)-O(2) bond lengths are 1.88 Å. Sb(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(2) atoms. All Sb(1)-O(2) bond lengths are 1.94 Å. There are two inequivalent O sites.
