Sr Ag Rh Rh Rh Rh
SrRh4Ag crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to three equivalent Rh(1), three equivalent Rh(2), and one Ag(1) atom. All Sr(1)-Rh(1) bond lengths are 3.27 Å. All Sr(1)-Rh(2) bond lengths are 3.19 Å. The Sr(1)-Ag(1) bond length is 1.41 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and three equivalent Rh(1) atoms. All Rh(2)-Rh(1) bond lengths are 1.08 Å. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to one Sr(1), one Rh(2), two equivalent Rh(1), and one Ag(1) atom. Both Rh(1)-Rh(1) bond lengths are 0.62 Å. The Rh(1)-Ag(1) bond length is 1.21 Å. Ag(1) is bonded in a distorted single-bond geometry to one Sr(1) and three equivalent Rh(1) atoms.
