Cr2AsSe crystallizes in the hexagonal P-6m2 space group. Cr(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), three equivalent As(1), and three equivalent Se(1) atoms. As(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms. Se(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms.
Cr2AsSe crystallizes in the hexagonal P-6m2 space group. Cr(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), three equivalent As(1), and three equivalent Se(1) atoms. There is one shorter (2.22 Å) and one longer (2.63 Å) Cr(1)-Cr(1) bond length. All Cr(1)-As(1) bond lengths are 2.50 Å. All Cr(1)-Se(1) bond lengths are 2.60 Å. As(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms. Se(1) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms.
