Tc Mo Mo
Mo2Tc crystallizes in the triclinic P1 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 2-coordinate geometry to one Mo(2) and two equivalent Tc(1) atoms. The Mo(1)-Mo(2) bond length is 3.04 Å. There is one shorter (1.98 Å) and one longer (2.38 Å) Mo(1)-Tc(1) bond length. In the second Mo site, Mo(2) is bonded in a 10-coordinate geometry to one Mo(1), six equivalent Mo(2), and three equivalent Tc(1) atoms. All Mo(2)-Mo(2) bond lengths are 2.79 Å. There are a spread of Mo(2)-Tc(1) bond distances ranging from 2.77-3.06 Å. Tc(1) is bonded in a 1-coordinate geometry to two equivalent Mo(1) and three equivalent Mo(2) atoms.
