The material described by 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. is represented by the CIF file [CIF]
