Materials Data on MgO by Materials Project

MgO is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Mg–O bond lengths are 2.13 Å. O2- is bonded to six equivalent Mg2+ atoms to form a mixture of edge and corner-sharing OMg6 octahedra. The corner-sharing octahedral tilt angles are 0°.氧化镁（MgO）具有岩盐型晶体结构，结晶于立方晶系Fm-3m空间群，其结构为三维空间框架。Mg²+与六个等价的O²-配位成键，形成MgO₆八面体，这些八面体以共边与共角两种方式相互连接。共角八面体的倾斜角为0°，所有Mg–O键长均为2.13埃。O²-与六个等价的Mg²+配位成键，形成OMg₆八面体，这些八面体同样以共边与共角两种方式相互连接，共角八面体的倾斜角为0°。
