Sr2NiTeO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Ni(1), four equivalent O(1), and four equivalent O(2) atoms. Ni(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(1) atoms. Te(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1), one Ni(1), and one Te(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1) and one Te(1) atom to form a mixture of distorted corner and edge-sharing OSr4Te trigonal bipyramids.
Sr2NiTeO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Ni(1), four equivalent O(1), and four equivalent O(2) atoms. The Sr(1)-Ni(1) bond length is 3.06 Å. All Sr(1)-O(1) bond lengths are 2.75 Å. There are two shorter (2.76 Å) and two longer (2.94 Å) Sr(1)-O(2) bond lengths. Ni(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(1) atoms. All Ni(1)-O(1) bond lengths are 1.89 Å. Te(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Te(1)-O(2) bond lengths are 1.97 Å. All Te(1)-O(1) bond lengths are 1.94 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1), one Ni(1), and one Te(1) atom.
