SrC4(SO)4 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing SrO6 octahedra. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted T-shaped geometry to one C(1), one C(2), and one S(1) atom. In the second C site, C(2) is bonded in a distorted T-shaped geometry to one C(1), one C(2), and one S(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 1-coordinate geometry to one C(1) and one O(2) atom. In the second S site, S(2) is bonded in a distorted water-like geometry to one C(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Sr(1) atoms. In the second O site, O(2) is bonded to two equivalent Sr(1) and two equivalent S(1) atoms to form corner-sharing OSr2S2 tetrahedra. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Sr(1) and one S(2) atom.
