BeMn(Ag)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag clusters and two BeMn clusters. In each Ag cluster, Ag(1) is bonded in a distorted single-bond geometry to one Ag(1) atom. The Ag(1)-Ag(1) bond length is 0.43 Å. In each BeMn cluster, Be(1) is bonded in a distorted single-bond geometry to one Mn(1) atom. The Be(1)-Mn(1) bond length is 0.43 Å. Mn(1) is bonded in a distorted single-bond geometry to one Be(1) atom.
