The structure described by (MgCrSF4)2F2 crystallizes in the triclinic P1 space group. The structure consists of two hydrofluoric acid atoms inside a MgCrSF4 framework. In the MgCrSF4 framework, there are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to one F(3), one F(7), and one F(8) atom. In the second Mg site, Mg(2) is bonded in a 1-coordinate geometry to one S(2), one F(1), one F(5), and one F(6) atom. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 2-coordinate geometry to one F(4), one F(5), and one F(7) atom. In the second Cr site, Cr(2) is bonded in a 4-coordinate geometry to one F(1), one F(3), one F(6), and one F(8) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 2-coordinate geometry to one F(2) and one F(5) atom. In the second S site, S(2) is bonded in a 2-coordinate geometry to one Mg(2) and one F(2) atom. There are eight inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to one Mg(2) and one Cr(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to one S(1) and one S(2) atom. In the third F site, F(3) is bonded in a bent 120 degrees geometry to one Mg(1) and one Cr(2) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one Cr(1) atom. In the fifth F site, F(5) is bonded in a 3-coordinate geometry to one Mg(2), one Cr(1), and one S(1) atom. In the sixth F site, F(6) is bonded in a distorted bent 150 degrees geometry to one Mg(2) and one Cr(2) atom. In the seventh F site, F(7) is bonded in a bent 150 degrees geometry to one Mg(1) and one Cr(1) atom. In the eighth F site, F(8) is bonded in a linear geometry to one Mg(1) and one Cr(2) atom. is represented by the CIF file [CIF]
