Materials Data on Rb3Si by Materials Project
Rb3Si crystallizes in the hexagonal P6_3/mmc space group. The structure is one-dimensional and consists of two Rb3Si ribbons oriented in the (0, 0, 1) direction. Rb is bonded in a distorted water-like geometry to two equivalent Si atoms. Both Rb–Si bond lengths are 3.79 Å. Si is bonded in a 6-coordinate geometry to six equivalent Rb atoms.
