MgAgF5 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded in a 6-coordinate geometry to one F(1), one F(3), one F(4), one F(5), and two equivalent F(2) atoms. Ag(1) is bonded to one F(1), one F(2), one F(3), one F(4), and two equivalent F(5) atoms to form corner-sharing AgF6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are five inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Mg(1) and one Ag(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to two equivalent Mg(1) and one Ag(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Mg(1) and one Ag(1) atom. In the fourth F site, F(4) is bonded in a linear geometry to one Mg(1) and one Ag(1) atom. In the fifth F site, F(5) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Ag(1) atoms.
