CdIn2Se4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Cd(1) is bonded to four equivalent Se(1) atoms to form CdSe4 tetrahedra that share corners with twelve equivalent In(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 58°. In(1) is bonded to six equivalent Se(1) atoms to form InSe6 octahedra that share corners with six equivalent Cd(1)Se4 tetrahedra and edges with six equivalent In(1)Se6 octahedra. Se(1) is bonded to one Cd(1) and three equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing SeCdIn3 trigonal pyramids.
