NaSrCrF6 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 6-coordinate geometry to one F(5), two equivalent F(2), two equivalent F(3), and two equivalent F(6) atoms. Sr(1) is bonded in a 8-coordinate geometry to one F(2), one F(3), one F(5), one F(6), two equivalent F(1), and two equivalent F(4) atoms. Cr(1) is bonded in an octahedral geometry to one F(1), one F(2), one F(3), one F(4), one F(5), and one F(6) atom. There are six inequivalent F sites. In the first F site, F(6) is bonded to two equivalent Na(1), one Sr(1), and one Cr(1) atom to form distorted edge-sharing FNa2SrCr trigonal pyramids. In the second F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr(1) and one Cr(1) atom. In the third F site, F(2) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Sr(1), and one Cr(1) atom. In the fourth F site, F(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Sr(1), and one Cr(1) atom.
