The material structure described by Cr2SiO4 crystallizes in the orthorhombic Fddd space group. Cr(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Si(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and one Si(1) atom. is represented by the CIF file [CIF]
