CuInSe2 is Enargite-like structured and crystallizes in the tetragonal P-4m2 space group. Cu(1) is bonded to four equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with four equivalent Cu(1)Se4 tetrahedra and corners with eight equivalent In(1)Se4 tetrahedra. In(1) is bonded to four equivalent Se(1) atoms to form InSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with eight equivalent Cu(1)Se4 tetrahedra. Se(1) is bonded to two equivalent Cu(1) and two equivalent In(1) atoms to form corner-sharing SeIn2Cu2 tetrahedra.

Cu(1) is bonded to four equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with four equivalent Cu(1)Se4 tetrahedra and corners with eight equivalent In(1)Se4 tetrahedra. All Cu(1)-Se(1) bond lengths are 2.44 Å. In(1) is bonded to four equivalent Se(1) atoms to form InSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with eight equivalent Cu(1)Se4 tetrahedra. All In(1)-Se(1) bond lengths are 2.65 Å. Se(1) is bonded to two equivalent Cu(1) and two equivalent In(1) atoms to form corner-sharing SeIn2Cu2 tetrahedra.
