The crystal structure described by Na2NiCSO7 crystallizes in the monoclinic P2_1/m space group. Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Ni(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(6) atoms to form NiO6 octahedra that share corners with four equivalent S(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. S(1) is bonded to one O(4), one O(5), and two equivalent O(6) atoms to form SO4 tetrahedra that share corners with four equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-52°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Na(1), one Ni(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted tetrahedral geometry to two equivalent Na(1), one Ni(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Ni(1), and one S(1) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Na(1), one Ni(1), and one S(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Na(1), one Ni(1), and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
