W2HgGa crystallizes in the monoclinic Cm space group. W(1) is bonded in a 4-coordinate geometry to four equivalent Hg(1) and two equivalent Ga(1) atoms. There are a spread of W(1)-Hg(1) bond distances ranging from 2.33-3.27 Å. There is one shorter (2.33 Å) and one longer (2.58 Å) W(1)-Ga(1) bond length. Hg(1) is bonded in a 11-coordinate geometry to eight equivalent W(1), two equivalent Hg(1), and one Ga(1) atom. Both Hg(1)-Hg(1) bond lengths are 2.85 Å. The Hg(1)-Ga(1) bond length is 2.82 Å. Ga(1) is bonded in a 4-coordinate geometry to four equivalent W(1) and one Hg(1) atom.
