The structure described by Ba(SO2)4 crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(8), and two equivalent O(7) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded in a single-bond geometry to one S(2) and one O(8) atom. In the second S site, S(2) is bonded in a water-like geometry to one S(1) and one S(4) atom. In the third S site, S(3) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the fourth S site, S(4) is bonded in a distorted trigonal non-coplanar geometry to one S(2), one O(4), one O(5), and one O(6) atom. There are eight inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Ba(1) and one S(4) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to one Ba(1) and one S(4) atom. In the third O site, O(6) is bonded in a single-bond geometry to one Ba(1) and one S(4) atom. In the fourth O site, O(7) is bonded in a bent 150 degrees geometry to two equivalent Ba(1) atoms.
