BaMgF4 crystallizes in the orthorhombic Cmc2_1 space group. Ba(1) is bonded in a 11-coordinate geometry to two equivalent F(3), three equivalent F(1), three equivalent F(2), and three equivalent F(4) atoms. Mg(1) is bonded to one F(2), one F(4), two equivalent F(1), and two equivalent F(3) atoms to form corner-sharing MgF6 octahedra. The corner-sharing octahedral tilt angles range from 7-27°. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to three equivalent Ba(1) and two equivalent Mg(1) atoms. In the second F site, F(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Mg(1) atom. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(1) and two equivalent Mg(1) atoms. In the fourth F site, F(4) is bonded in a 1-coordinate geometry to three equivalent Ba(1) and one Mg(1) atom.
BaMgF4 crystallizes in the orthorhombic Cmc2_1 space group. Ba(1) is bonded in a 11-coordinate geometry to two equivalent F(3), three equivalent F(1), three equivalent F(2), and three equivalent F(4) atoms. Both Ba(1)-F(3) bond lengths are 2.88 Å. There are a spread of Ba(1)-F(1) bond distances ranging from 2.85-3.29 Å. There is one shorter (2.66 Å) and two longer (2.68 Å) Ba(1)-F(2) bond lengths. There are two shorter (2.62 Å) and one longer (2.99 Å) Ba(1)-F(4) bond length. Mg(1) is bonded to one F(2), one F(4), two equivalent F(1), and two equivalent F(3) atoms to form corner-sharing MgF6 octahedra. The corner-sharing octahedral tilt angles range from 7-27°.
