TcHg2Zn crystallizes in the triclinic P1 space group. Tc(1) is bonded in a 2-coordinate geometry to two equivalent Hg(2), four equivalent Hg(1), and two equivalent Zn(1) atoms. There is one shorter (2.75 Å) and one longer (3.10 Å) Tc(1)-Hg(2) bond length. There are a spread of Tc(1)-Hg(1) bond distances ranging from 2.78-3.10 Å. There is one shorter (2.55 Å) and one longer (2.60 Å) Tc(1)-Zn(1) bond length. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 10-coordinate geometry to four equivalent Tc(1), two equivalent Hg(1), two equivalent Hg(2), and two equivalent Zn(1) atoms. Both Hg(1)-Hg(1) bond lengths are 2.97 Å. There is one shorter (2.55 Å) and one longer (2.60 Å) Hg(1)-Hg(2) bond length. Both Hg(1)-Zn(1) bond lengths are 2.98 Å. In the second Hg site, Hg(2) is bonded in a 10-coordinate geometry to two equivalent Tc(1), two equivalent Hg(1), two equivalent Hg(2), and four equivalent Zn(1) atoms. Both Hg(2)-Hg(2) bond lengths are 2.97 Å. There are a spread of Hg(2)-Zn(1) bond distances ranging from 2.78-3.10 Å. Zn(1) is bonded in a 8-coordinate geometry to two equivalent Tc(1), two equivalent Hg(1), and four equivalent Hg(2) atoms.
