Ho Ag Ag
Ag2Ho crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2Ho clusters. Ho(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ho(1)-Ag(1) bond length is 0.29 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ho(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 0.61 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Ag(1) atom.
