Materials Data on Rb2SiAs2 by Materials Project
Rb2SiAs2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. There are a spread of Rb–As bond distances ranging from 3.56–3.82 Å. Si4+ is bonded to four equivalent As3- atoms to form distorted edge-sharing SiAs4 tetrahedra. All Si–As bond lengths are 2.41 Å. As3- is bonded in a 2-coordinate geometry to six equivalent Rb1+ and two equivalent Si4+ atoms.
