Cu2Se is Fluorite structured and crystallizes in the orthorhombic Imm2 space group. Cu(1) is bonded in a distorted trigonal planar geometry to three equivalent Se(1) atoms. Se(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms.
Cu2Se is Fluorite structured and crystallizes in the orthorhombic Imm2 space group. Cu(1) is bonded in a distorted trigonal planar geometry to three equivalent Se(1) atoms. There is one shorter (2.38 Å) and two longer (2.46 Å) Cu(1)-Se(1) bond lengths. Se(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms.
