Materials Data on Zn2SiO4 by Materials Project

Zn2SiO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with six equivalent ZnO6 octahedra. All Zn–O bond lengths are 2.13 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with twelve equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Si–O bond lengths are 1.68 Å. O2- is bonded in a rectangular see-saw-like geometry to three equivalent Zn2+ and one Si4+ atom.

硅酸锌（Zn₂SiO₄）具有尖晶石（Spinel）结构，结晶于立方晶系Fd-3m空间群。该结构为三维框架结构。Zn²+与六个等价的O²-原子配位，形成ZnO₆八面体，该八面体与六个等价的SiO₄四面体共享顶点，同时与六个等价的ZnO₆八面体共享棱边。所有Zn–O键长均为2.13 Å。Si⁴+与四个等价的O²-原子配位，形成SiO₄四面体，该四面体与十二个等价的ZnO₆八面体共享顶点。共顶点八面体的倾斜角为52°。所有Si–O键长均为1.68 Å。O²-以矩形跷板式配位几何构型，与三个等价的Zn²+以及一个Si⁴+原子成键。
