Si is beta Sn structured and crystallizes in the tetragonal I4_1/amd space group. Si(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms.
Si is beta Sn structured and crystallizes in the tetragonal I4_1/amd space group. Si(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. There are four shorter (2.46 Å) and two longer (2.66 Å) Si(1)-Si(1) bond lengths.
