AgCrSe2 is Ilmenite-like structured and crystallizes in the trigonal R3m space group. Cr(1) is bonded to three equivalent Se(1) and three equivalent Se(2) atoms to form distorted edge-sharing CrSe6 pentagonal pyramids. Ag(1) is bonded in a 4-coordinate geometry to one Se(1) and three equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Cr(1) and one Ag(1) atom. In the second Se site, Se(2) is bonded to three equivalent Cr(1) and three equivalent Ag(1) atoms to form edge-sharing SeCr3Ag3 octahedra.
