CaLaAg4 is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three CaLaAg4 clusters. Ca(1) is bonded in a single-bond geometry to one La(1) atom. The Ca(1)-La(1) bond length is 0.88 Å. La(1) is bonded in a distorted rectangular see-saw-like geometry to one Ca(1) and three equivalent Ag(1) atoms. All La(1)-Ag(1) bond lengths are 0.75 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent Ag(1) atoms. All Ag(2)-Ag(1) bond lengths are 0.73 Å. In the second Ag site, Ag(1) is bonded in a 3-coordinate geometry to one La(1), one Ag(2), and two equivalent Ag(1) atoms. Both Ag(1)-Ag(1) bond lengths are 0.42 Å.
