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 4-coordinate geometry to four equivalent F(1) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent F(1) and six equivalent F(2) atoms. Rh(1) is bonded in a distorted body-centered cubic geometry to four equivalent F(1) and four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Sr(1), one Sr(2), and one Rh(1) atom. In the second F site, F(2) is bonded in a 2-coordinate geometry to three equivalent Sr(2) atoms. In the third F site, F(3) is bonded in a single-bond geometry to one Rh(1) atom.
