Mo2TcBi crystallizes in the triclinic P1 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a distorted single-bond geometry to one Mo(2), one Tc(1), and two equivalent Bi(1) atoms. The Mo(1)-Mo(2) bond length is 1.13 Å. The Mo(1)-Tc(1) bond length is 0.72 Å. There is one shorter (2.67 Å) and one longer (3.55 Å) Mo(1)-Bi(1) bond length. In the second Mo site, Mo(2) is bonded in a 1-coordinate geometry to one Mo(1) and two equivalent Bi(1) atoms. There is one shorter (2.72 Å) and one longer (3.11 Å) Mo(2)-Bi(1) bond length. Tc(1) is bonded in a single-bond geometry to one Mo(1) and three equivalent Bi(1) atoms. There are a spread of Tc(1)-Bi(1) bond distances ranging from 2.90-3.49 Å. Bi(1) is bonded in a 9-coordinate geometry to two equivalent Mo(1), two equivalent Mo(2), three equivalent Tc(1), and two equivalent Bi(1) atoms. Both Bi(1)-Bi(1) bond lengths are 3.19 Å.
