The crystal structure described by MgO is Tungsten Carbide structured and crystallizes in the hexagonal P-6m2 space group. Mg(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner, edge, and face-sharing MgO6 pentagonal pyramids. O(1) is bonded to six equivalent Mg(1) atoms to form a mixture of distorted corner, edge, and face-sharing OMg6 pentagonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
