Be Hg Pd Pd
BePd2Hg crystallizes in the triclinic P1 space group. Be(1) is bonded in a single-bond geometry to two equivalent Pd(1), two equivalent Pd(2), and one Hg(1) atom. Both Be(1)-Pd(1) bond lengths are 2.58 Å. There is one shorter (2.88 Å) and one longer (2.89 Å) Be(1)-Pd(2) bond length. The Be(1)-Hg(1) bond length is 0.46 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 3-coordinate geometry to two equivalent Be(1) and two equivalent Pd(2) atoms. There is one shorter (1.97 Å) and one longer (2.62 Å) Pd(1)-Pd(2) bond length. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to two equivalent Be(1), two equivalent Pd(1), two equivalent Pd(2), and two equivalent Hg(1) atoms. Both Pd(2)-Pd(2) bond lengths are 3.00 Å. Both Pd(2)-Hg(1) bond lengths are 2.58 Å. Hg(1) is bonded in a single-bond geometry to one Be(1) and two equivalent Pd(2) atoms.
