Cr5Se8In crystallizes in the monoclinic C2/m space group. The structure consists of two 7440-74-6 atoms inside a Cr5Se8 framework. In the Cr5Se8 framework, there are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent Se(3) and four equivalent Se(4) atoms to form a mixture of corner and edge-sharing CrSe6 octahedra. The corner-sharing octahedral tilt angles are 49°. In the second Cr site, Cr(2) is bonded to one Se(4), two equivalent Se(2), and three equivalent Se(1) atoms to form a mixture of corner, face, and edge-sharing CrSe6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. In the third Cr site, Cr(3) is bonded to one Se(4), two equivalent Se(3), and three equivalent Se(2) atoms to form a mixture of corner, face, and edge-sharing CrSe6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted T-shaped geometry to three equivalent Cr(2) atoms. In the second Se site, Se(2) is bonded to two equivalent Cr(2) and three equivalent Cr(3) atoms to form distorted edge-sharing SeCr5 trigonal bipyramids. In the third Se site, Se(3) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Cr(3) atoms. In the fourth Se site, Se(4) is bonded in a rectangular see-saw-like geometry to one Cr(2), one Cr(3), and two equivalent Cr(1) atoms.

In the first Cr site, Cr(1) is bonded to two equivalent Se(3) and four equivalent Se(4) atoms to form a mixture of corner and edge-sharing CrSe6 octahedra. The corner-sharing octahedral tilt angles are 49°. Both Cr(1)-Se(3) bond lengths are 2.53 Å. All Cr(1)-Se(4) bond lengths are 2.53 Å. In the second Cr site, Cr(2) is bonded to one Se(4), two equivalent Se(2), and three equivalent Se(1) atoms to form a mixture of corner, face, and edge-sharing CrSe6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. The Cr(2)-Se(4) bond length is 2.57 Å. Both Cr(2)-Se(2) bond lengths are 2.63 Å. There is one shorter (2.50 Å) and two longer (2.51 Å) Cr(2)-Se(1) bond lengths. In the third Cr site, Cr(3) is bonded to one Se(4), two equivalent Se(3), and three equivalent Se(2) atoms to form a mixture of corner, face, and edge-sharing CrSe6 octahedra.

There is one shorter (2.56 Å) and two longer (2.66 Å) Cr(3)-Se(2) bond lengths. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted T-shaped geometry to three equivalent Cr(2) atoms.
