The structure described by Cu2S crystallizes in the tetragonal P4_32_12 space group. Cu(1) is bonded in a distorted trigonal planar geometry to three equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
