Materials Data on CaMgPb by Materials Project
CaMgPb crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ca is bonded in a 5-coordinate geometry to five equivalent Pb atoms. There are a spread of Ca–Pb bond distances ranging from 3.32–3.44 Å. Mg is bonded to four equivalent Pb atoms to form a mixture of distorted edge and corner-sharing MgPb4 tetrahedra. There are a spread of Mg–Pb bond distances ranging from 2.96–3.07 Å. Pb is bonded in a 9-coordinate geometry to five equivalent Ca and four equivalent Mg atoms.
