Materials Data on Fe2SiO4 by Materials Project

Fe2SiO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Fe2+ is bonded to six equivalent O2- atoms to form FeO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with six equivalent FeO6 octahedra. All Fe–O bond lengths are 2.17 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with twelve equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Si–O bond lengths are 1.67 Å. O2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Fe2+ and one Si4+ atom.

Fe₂SiO₄ 具有尖晶石结构（Spinel structure），结晶于立方晶系Fd-3m空间群。该结构为三维空间框架。Fe²+ 与六个等价的O²- 配位形成FeO₆八面体，该八面体与六个等价的SiO₄四面体共享角顶，同时与六个等价的FeO₆八面体共享棱边。所有Fe–O键长均为2.17 Å。Si⁴+ 与四个等价的O²- 配位形成SiO₄四面体，该四面体与十二个等价的FeO₆八面体共享角顶。共顶八面体的倾斜角为52°。所有Si–O键长均为1.67 Å。O²- 以畸变的矩形跷跷板型配位几何与三个等价的Fe²+ 以及一个Si⁴+ 原子成键。
