Materials Data on BeI2 by Materials Project

BeI2 is Silicon Disuphide structured and crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of two BeI2 ribbons oriented in the (1, 0, 0) direction. Be2+ is bonded to four equivalent I1- atoms to form edge-sharing BeI4 tetrahedra. All Be–I bond lengths are 2.43 Å. I1- is bonded in a distorted L-shaped geometry to two equivalent Be2+ atoms.
