Ca Mn Ag Ag
CaMnAg2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaMnAg2 clusters. Ca(1) is bonded in a distorted single-bond geometry to one Ag(2) atom. The Ca(1)-Ag(2) bond length is 1.52 Å. Mn(1) is bonded in a single-bond geometry to one Ag(1) and one Ag(2) atom. The Mn(1)-Ag(1) bond length is 1.58 Å. The Mn(1)-Ag(2) bond length is 0.04 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Mn(1) atom. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Ca(1) and one Mn(1) atom.
