Cu2Se crystallizes in the tetragonal P4_32_12 space group. Cu(1) is bonded in a distorted trigonal planar geometry to three equivalent Se(1) atoms. Se(1) is bonded to six equivalent Cu(1) atoms to form distorted corner-sharing SeCu6 pentagonal pyramids.
Cu2Se crystallizes in the tetragonal P4_32_12 space group. Cu(1) is bonded in a distorted trigonal planar geometry to three equivalent Se(1) atoms. There is one shorter (2.41 Å) and two longer (2.42 Å) Cu(1)-Se(1) bond lengths. Se(1) is bonded to six equivalent Cu(1) atoms to form distorted corner-sharing SeCu6 pentagonal pyramids.
