BaCoSO crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Co(1) is bonded to two equivalent S(1) and two equivalent O(1) atoms to form distorted corner-sharing CoS2O2 tetrahedra. S(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and two equivalent Co(1) atoms. O(1) is bonded to four equivalent Ba(1) and two equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing OBa4Co2 octahedra. The corner-sharing octahedral tilt angles are 60°.
BaCoSO crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. There are two shorter (3.24 Å) and two longer (3.25 Å) Ba(1)-S(1) bond lengths. All Ba(1)-O(1) bond lengths are 2.93 Å. Co(1) is bonded to two equivalent S(1) and two equivalent O(1) atoms to form distorted corner-sharing CoS2O2 tetrahedra. Both Co(1)-S(1) bond lengths are 2.37 Å. Both Co(1)-O(1) bond lengths are 1.97 Å. S(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and two equivalent Co(1) atoms.
