Ca Cr Cr Ag
CaCr2Ag crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CaCr2Ag cluster. Ca(1) is bonded in a single-bond geometry to one Cr(1) atom. The Ca(1)-Cr(1) bond length is 0.59 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a linear geometry to one Ca(1) and one Ag(1) atom. The Cr(1)-Ag(1) bond length is 0.15 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Ag(1) atom. The Cr(2)-Ag(1) bond length is 1.34 Å. Ag(1) is bonded in a distorted single-bond geometry to one Cr(1) and one Cr(2) atom.
