Fe Fe Ag Bi
FeAgBiFe1 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two bismuthanylidyneiron molecules and two FeAg clusters. In each FeAg cluster, Fe(1) is bonded in a 1-coordinate geometry to one Ag(1) atom. The Fe(1)-Ag(1) bond length is 1.64 Å. Ag(1) is bonded in a single-bond geometry to one Fe(1) atom.
