Materials Data on CsFeSiO4 by Materials Project
CsFeSiO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.54 Å. Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.86–1.91 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent FeO4 tetrahedra. There is two shorter (1.64 Å) and two longer (1.65 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Cs1+, one Fe3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Fe3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Fe3+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+, one Fe3+, and one Si4+ atom.
