Ag3Ca5 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a distorted square co-planar geometry to two equivalent Ag(1) and four equivalent Ag(2) atoms. In the second Ca site, Ca(2) is bonded to two equivalent Ag(1) and three equivalent Ag(2) atoms to form a mixture of distorted corner, edge, and face-sharing CaAg5 trigonal bipyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to two equivalent Ca(1) and eight equivalent Ca(2) atoms. In the second Ag site, Ag(2) is bonded in a 9-coordinate geometry to two equivalent Ca(1), six equivalent Ca(2), and one Ag(2) atom.
Ag3Ca5 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a distorted square co-planar geometry to two equivalent Ag(1) and four equivalent Ag(2) atoms. Both Ca(1)-Ag(1) bond lengths are 3.75 Å. All Ca(1)-Ag(2) bond lengths are 3.15 Å. In the second Ca site, Ca(2) is bonded to two equivalent Ag(1) and three equivalent Ag(2) atoms to form a mixture of distorted corner, edge, and face-sharing CaAg5 trigonal bipyramids. Both Ca(2)-Ag(1) bond lengths are 3.35 Å. There is one shorter (3.17 Å) and two longer (3.22 Å) Ca(2)-Ag(2) bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to two equivalent Ca(1) and eight equivalent Ca(2) atoms. In the second Ag site, Ag(2) is bonded in a 9-coordinate geometry to two equivalent Ca(1), six equivalent Ca(2), and one Ag(2) atom. The Ag(2)-Ag(2) bond length is 2.81 Å.
