Ge Mo Mo Pb
Mo2PbGe crystallizes in the monoclinic Cm space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 1-coordinate geometry to one Pb(1) and three equivalent Ge(1) atoms. The Mo(1)-Pb(1) bond length is 2.14 Å. There is one shorter (2.79 Å) and two longer (3.22 Å) Mo(1)-Ge(1) bond lengths. In the second Mo site, Mo(2) is bonded in a 1-coordinate geometry to one Pb(1) and three equivalent Ge(1) atoms. The Mo(2)-Pb(1) bond length is 2.14 Å. There is one shorter (2.85 Å) and two longer (3.28 Å) Mo(2)-Ge(1) bond lengths. Pb(1) is bonded in a 2-coordinate geometry to one Mo(1) and one Mo(2) atom. Ge(1) is bonded in a 6-coordinate geometry to three equivalent Mo(1) and three equivalent Mo(2) atoms.
