Materials Data on AlSiO3 by Materials Project

AlSiO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Al is bonded to twelve equivalent O atoms to form AlO12 cuboctahedra that share corners with twelve equivalent AlO12 cuboctahedra, faces with six equivalent AlO12 cuboctahedra, and faces with eight equivalent SiO6 octahedra. All Al–O bond lengths are 2.52 Å. Si is bonded to six equivalent O atoms to form SiO6 octahedra that share corners with six equivalent SiO6 octahedra and faces with eight equivalent AlO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Si–O bond lengths are 1.78 Å. O is bonded in a linear geometry to four equivalent Al and two equivalent Si atoms.AlSiO₃ 具有立方钙钛矿（Cubic Perovskite）结构，结晶于立方晶系Pm-3m空间群。该结构为三维骨架结构。Al原子与12个等价的O原子成键，形成AlO₁₂立方八面体配位多面体；该配位多面体分别与12个等价AlO₁₂立方八面体共享顶点、与6个等价AlO₁₂立方八面体共享面，同时与8个等价SiO₆八面体共享面。所有Al–O键长均为2.52 Å。Si原子与6个等价的O原子成键，形成SiO₆八面体配位多面体；该八面体与6个等价SiO₆八面体共享顶点，同时与8个等价AlO₁₂立方八面体共享面。共顶点八面体的倾斜角为0°。所有Si–O键长均为1.78 Å。O原子以直线型配位构型与4个等价Al原子及2个等价Si原子成键。
