Ag Ag Ge Bi
Ag2GeBi is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2GeBi clusters. Ag(1) is bonded in a 2-coordinate geometry to one Ge(1) and one Bi(1) atom. The Ag(1)-Ge(1) bond length is 1.30 Å. The Ag(1)-Bi(1) bond length is 1.30 Å. Ge(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. Bi(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms.
