K2MgO2 is alpha Pu-derived structured and crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Mg(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing MgO4 tetrahedra. O(1) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Mg(1) atoms.
K2MgO2 is alpha Pu-derived structured and crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are a spread of K(1)-O(1) bond distances ranging from 2.64-2.85 Å. Mg(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing MgO4 tetrahedra. There are two shorter (1.99 Å) and two longer (2.00 Å) Mg(1)-O(1) bond lengths. O(1) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Mg(1) atoms.
