MgCd2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded to ten Cd(1,1,1) atoms to form a mixture of distorted corner, face, and edge-sharing MgCd10 cuboctahedra. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1) atoms. In the second Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1) atoms. In the third Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1,1) atoms.
MgCd2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded to ten Cd(1,1,1) atoms to form a mixture of distorted corner, face, and edge-sharing MgCd10 cuboctahedra. There are a spread of Mg(1)-Cd(1,1,1) bond distances ranging from 3.01-3.18 Å. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1) atoms. There are a spread of Cd(1)-Cd(1,1) bond distances ranging from 3.00-3.27 Å. In the second Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1) atoms. There are a spread of Cd(1)-Cd(1) bond distances ranging from 3.00-3.26 Å. In the third Cd site, Cd(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Cd(1,1,1) atoms. There is one shorter (3.08 Å) and two longer (3.27 Å) Cd(1)-Cd(1) bond lengths.
