The structure described by Sr3MnF12 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 distorted body-centered cubic geometry to four equivalent F(1) and four equivalent F(3) 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. Mn(1) is bonded in a square co-planar geometry to four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one Sr(1) and one Sr(2) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to three equivalent Sr(2) atoms. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Sr(1) and one Mn(1) atom. is represented by the CIF card [CIF]
