Materials Data on Sr7Ag3 by Materials Project
Sr7Ag3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Sr sites. In the first Sr site, Sr is bonded in a 3-coordinate geometry to three equivalent Ag atoms. All Sr–Ag bond lengths are 3.27 Å. In the second Sr site, Sr is bonded in a distorted L-shaped geometry to two equivalent Ag atoms. Both Sr–Ag bond lengths are 3.33 Å. In the third Sr site, Sr is bonded in a distorted T-shaped geometry to three equivalent Ag atoms. There are two shorter (3.31 Å) and one longer (3.33 Å) Sr–Ag bond lengths. Ag is bonded in a 6-coordinate geometry to six Sr atoms.
