Re Ge Pb
RePbGe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RePbGe clusters. Re(1) is bonded in a single-bond geometry to one Pb(1) atom. The Re(1)-Pb(1) bond length is 1.14 Å. Pb(1) is bonded in a linear geometry to one Re(1) and one Ge(1) atom. The Pb(1)-Ge(1) bond length is 0.15 Å. Ge(1) is bonded in a single-bond geometry to one Pb(1) atom.
