Cr2SeS is Caswellsilverite-like structured and crystallizes in the hexagonal P-6m2 space group. Cr(1) is bonded to three equivalent Se(1) and three equivalent S(1) atoms to form a mixture of corner, edge, and face-sharing CrSe3S3 octahedra. The corner-sharing octahedral tilt angles range from 47-49°. Se(1) is bonded to six equivalent Cr(1) atoms to form distorted edge-sharing SeCr6 pentagonal pyramids. S(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms.
