BaC2S2(NO)2 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(2), one S(1), one S(2), one O(1), and one O(2) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one N(1) and one S(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one N(2) and one S(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one Ba(1) and one C(1) atom. In the second S site, S(2) is bonded in a distorted single-bond geometry to one Ba(1) and one C(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ba(1) and one O(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ba(1) and one O(2) atom.
