The structure described by Sr2RhF7 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to one F(2), one F(3), one F(5), one F(6), one F(7), two equivalent F(1), and two equivalent F(4) atoms. In the second Sr site, Sr(2) is bonded in a 10-coordinate geometry to one F(1), one F(2), one F(3), one F(4), two equivalent F(5), two equivalent F(6), and two equivalent F(7) atoms. Rh(1) is bonded in an octahedral geometry to one F(2), one F(3), one F(4), one F(5), one F(6), and one F(7) atom. There are seven inequivalent F sites. In the first F site, F(6) is bonded to one Sr(1), two equivalent Sr(2), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing FSr3Rh tetrahedra. In the second F site, F(7) is bonded to one Sr(1), two equivalent Sr(2), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing FSr3Rh trigonal pyramids. In the third F site, F(1) is bonded in a trigonal planar geometry to one Sr(2) and two equivalent Sr(1) atoms. In the fourth F site, F(2) is bonded in a distorted trigonal planar geometry to one Sr(1), one Sr(2), and one Rh(1) atom. In the fifth F site, F(3) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1), one Sr(2), and one Rh(1) atom. In the sixth F site, F(4) is bonded in a 4-coordinate geometry to one Sr(2), two equivalent Sr(1), and one Rh(1) atom. In the seventh F site, F(5) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Sr(2), and one Rh(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
