CaMg2Pd crystallizes in the trigonal R3m space group. Ca(1) is bonded in a 8-coordinate geometry to four equivalent Mg(2) and four equivalent Pd(1) atoms. There is one shorter (2.89 Å) and three longer (3.11 Å) Ca(1)-Mg(2) bond lengths. There is one shorter (2.89 Å) and three longer (3.11 Å) Ca(1)-Pd(1) bond lengths. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to four equivalent Mg(2) and three equivalent Pd(1) atoms. There is one shorter (2.89 Å) and three longer (3.11 Å) Mg(1)-Mg(2) bond lengths. All Mg(1)-Pd(1) bond lengths are 2.93 Å. In the second Mg site, Mg(2) is bonded in a 11-coordinate geometry to four equivalent Ca(1), four equivalent Mg(1), and three equivalent Pd(1) atoms. All Mg(2)-Pd(1) bond lengths are 3.34 Å. Pd(1) is bonded in a 7-coordinate geometry to four equivalent Ca(1), three equivalent Mg(1), and three equivalent Mg(2) atoms.
