Zn Hg Pd Pd
Pd2HgZn is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pd2HgZn clusters. Pd(1) is bonded in a 3-coordinate geometry to one Pd(1), one Hg(1), and one Zn(1) atom. The Pd(1)-Pd(1) bond length is 0.53 Å. The Pd(1)-Hg(1) bond length is 0.44 Å. The Pd(1)-Zn(1) bond length is 0.88 Å. Hg(1) is bonded in a distorted L-shaped geometry to two equivalent Pd(1) atoms. Zn(1) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms.
