The structure described by CaMgPb crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. Mg(1) is bonded to four equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing MgPb4 tetrahedra. Pb(1) is bonded in a 9-coordinate geometry to five equivalent Ca(1) and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
