The material described by Cr2TeSe is Caswellsilverite-like structured and crystallizes in the hexagonal P-6m2 space group. Cr(1) is bonded to three equivalent Te(1) and three equivalent Se(1) atoms to form a mixture of edge, face, and corner-sharing CrTe3Se3 octahedra. The corner-sharing octahedral tilt angles range from 48-49°. Te(1) is bonded to six equivalent Cr(1) atoms to form distorted edge-sharing TeCr6 pentagonal pyramids. Se(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
