Nd2O2SO4 crystallizes in the tetragonal I-42m space group. Nd(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted NdO6 pentagonal pyramids that share corners with four equivalent Nd(1)O6 pentagonal pyramids, corners with two equivalent S(1)O4 tetrahedra, and edges with four equivalent Nd(1)O6 pentagonal pyramids. S(1) is bonded to four equivalent O(1) atoms to form SO4 tetrahedra that share corners with four equivalent Nd(1)O6 pentagonal pyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra. In the second O site, O(1) is bonded in a linear geometry to one Nd(1) and one S(1) atom.

Both Nd(1)-O(1) bond lengths are 2.42 Å. All Nd(1)-O(2) bond lengths are 2.36 Å. S(1) is bonded to four equivalent O(1) atoms to form SO4 tetrahedra that share corners with four equivalent Nd(1)O6 pentagonal pyramids. All S(1)-O(1) bond lengths are 1.47 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra.
