Mg3Pd crystallizes in the hexagonal P6_3cm space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pd(1) atoms. In the second Mg site, Mg(2) is bonded in a trigonal planar geometry to three equivalent Pd(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted trigonal planar geometry to three equivalent Pd(1) atoms. Pd(1) is bonded in a 8-coordinate geometry to one Mg(1), two equivalent Mg(2), two equivalent Mg(3), and three equivalent Mg(4) atoms.
Mg3Pd crystallizes in the hexagonal P6_3cm space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pd(1) atoms. All Mg(1)-Pd(1) bond lengths are 2.69 Å. In the second Mg site, Mg(2) is bonded in a trigonal planar geometry to three equivalent Pd(1) atoms. All Mg(2)-Pd(1) bond lengths are 2.72 Å. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms. There is one shorter (2.74 Å) and one longer (2.76 Å) Mg(3)-Pd(1) bond length. In the fourth Mg site, Mg(4) is bonded in a distorted trigonal planar geometry to three equivalent Pd(1) atoms. There is one shorter (2.75 Å) and two longer (2.84 Å) Mg(4)-Pd(1) bond lengths. Pd(1) is bonded in a 8-coordinate geometry to one Mg(1), two equivalent Mg(2), two equivalent Mg(3), and three equivalent Mg(4) atoms.
