Ge Mo Mo Pb
Mo2PbGe crystallizes in the monoclinic Cm space group. Mo(1) is bonded in a single-bond geometry to one Pb(1) and two equivalent Ge(1) atoms. The Mo(1)-Pb(1) bond length is 1.38 Å. There is one shorter (2.40 Å) and one longer (2.79 Å) Mo(1)-Ge(1) bond length. Pb(1) is bonded in a distorted water-like geometry to two equivalent Mo(1) and two equivalent Ge(1) atoms. There is one shorter (2.24 Å) and one longer (2.60 Å) Pb(1)-Ge(1) bond length. Ge(1) is bonded in a 6-coordinate geometry to four equivalent Mo(1) and two equivalent Pb(1) atoms.
