Co2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Co(1) is bonded to six equivalent S(1) atoms to form a mixture of corner, edge, and face-sharing CoS6 octahedra. The corner-sharing octahedral tilt angles range from 47-60°. S(1) is bonded to four equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing SCo4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-60°. There are three shorter (2.22 Å) and three longer (2.28 Å) Co(1)-S(1) bond lengths. S(1) is bonded to four equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing SCo4 trigonal pyramids.
