WTc2Zn crystallizes in the triclinic P1 space group. W(1) is bonded in a 2-coordinate geometry to two equivalent Tc(2) and two equivalent Zn(1) atoms. There is one shorter (2.40 Å) and one longer (2.50 Å) W(1)-Tc(2) bond length. There is one shorter (2.97 Å) and one longer (3.05 Å) W(1)-Zn(1) bond length. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 2-coordinate geometry to two equivalent Tc(2) and two equivalent Zn(1) atoms. There is one shorter (1.98 Å) and one longer (2.10 Å) Tc(1)-Tc(2) bond length. There is one shorter (2.93 Å) and one longer (3.02 Å) Tc(1)-Zn(1) bond length. In the second Tc site, Tc(2) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent Tc(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to two equivalent W(1), two equivalent Tc(1), and four equivalent Zn(1) atoms. All Zn(1)-Zn(1) bond lengths are 2.69 Å.
