BePd2Hg crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to three equivalent Pd(1) and one Hg(1) atom. All Be(1)-Pd(1) bond lengths are 2.78 Å. The Be(1)-Hg(1) bond length is 1.47 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to three equivalent Be(1), one Pd(2), and three equivalent Hg(1) atoms. The Pd(1)-Pd(2) bond length is 1.47 Å. All Pd(1)-Hg(1) bond lengths are 2.78 Å. In the second Pd site, Pd(2) is bonded in a 1-coordinate geometry to one Pd(1) atom. Hg(1) is bonded in a single-bond geometry to one Be(1) and three equivalent Pd(1) atoms.
