Re Re Hg Bi
Re2HgBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Re2HgBi clusters. Re(1) is bonded in a 2-coordinate geometry to one Hg(1) and one Bi(1) atom. The Re(1)-Hg(1) bond length is 1.91 Å. The Re(1)-Bi(1) bond length is 1.91 Å. Hg(1) is bonded in a 2-coordinate geometry to two equivalent Re(1) atoms. Bi(1) is bonded in a 2-coordinate geometry to two equivalent Re(1) atoms.
