TaPdHg crystallizes in the triclinic P1 space group. Ta(1) is bonded in a distorted single-bond geometry to one Pd(1) and three equivalent Hg(1) atoms. The Ta(1)-Pd(1) bond length is 1.44 Å. There are a spread of Ta(1)-Hg(1) bond distances ranging from 3.11-3.60 Å. Pd(1) is bonded in a distorted single-bond geometry to one Ta(1) and one Hg(1) atom. The Pd(1)-Hg(1) bond length is 3.45 Å. Hg(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), one Pd(1), and six equivalent Hg(1) atoms. All Hg(1)-Hg(1) bond lengths are 2.97 Å.
