Materials Data on SrAg5 by Materials Project
SrAg5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sr is bonded in a distorted hexagonal planar geometry to eighteen Ag atoms. There are six shorter (3.33 Å) and twelve longer (3.72 Å) Sr–Ag bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag is bonded in a 12-coordinate geometry to three equivalent Sr and six equivalent Ag atoms. All Ag–Ag bond lengths are 2.88 Å. In the second Ag site, Ag is bonded to four equivalent Sr and eight Ag atoms to form a mixture of edge, face, and corner-sharing AgSr4Ag8 cuboctahedra. All Ag–Ag bond lengths are 2.88 Å.
