The material structure described by BaMgAgF7 crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 12-coordinate geometry to one F(1), one F(2), two equivalent F(3), two equivalent F(4), two equivalent F(5), two equivalent F(6), and two equivalent F(7) atoms. Mg(1) is bonded to one F(1), one F(2), one F(3), one F(5), one F(6), and one F(7) atom to form MgF6 octahedra that share corners with three equivalent Ag(1)F6 octahedra and  an edgeedge with one Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 52-57°. Ag(1) is bonded to one F(1), one F(2), one F(3), one F(4), one F(5), and one F(6) atom to form AgF6 octahedra that share corners with three equivalent Mg(1)F6 octahedra and  an edgeedge with one Mg(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 52-57°. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Mg(1), and one Ag(1) atom. In the second F site, F(2) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Mg(1), and one Ag(1) atom. In the third F site, F(3) is bonded in a distorted water-like geometry to two equivalent Ba(1), one Mg(1), and one Ag(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Ba(1) and one Ag(1) atom. In the fifth F site, F(5) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(1), one Mg(1), and one Ag(1) atom. In the sixth F site, F(6) is bonded in a distorted water-like geometry to two equivalent Ba(1), one Mg(1), and one Ag(1) atom.
