CrS2 is trigonal omega-like structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form edge-sharing CrS6 octahedra. In the second Cr site, Cr(2) is bonded to six equivalent S(1) atoms to form edge-sharing CrS6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to one Cr(2) and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded in a distorted T-shaped geometry to three equivalent Cr(1) atoms.

In the first Cr site, Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form edge-sharing CrS6 octahedra. Both Cr(1)-S(2) bond lengths are 2.36 Å. All Cr(1)-S(1) bond lengths are 2.35 Å. In the second Cr site, Cr(2) is bonded to six equivalent S(1) atoms to form edge-sharing CrS6 octahedra. All Cr(2)-S(1) bond lengths are 2.33 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to one Cr(2) and two equivalent Cr(1) atoms.
