Sr3RhF12 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to four equivalent F(2) and four equivalent F(3) atoms. In the second Sr site, Sr(2) is bonded in a body-centered cubic geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Rh(1) is bonded in a body-centered cubic geometry to four equivalent F(2) and four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a water-like geometry to two equivalent Sr(2) atoms. In the second F site, F(2) is bonded in a distorted T-shaped geometry to one Sr(1), one Sr(2), and one Rh(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Rh(1) atom.
